How 5G is enhancing communication in critical sectors

Luke Wilkinson, MD, Mobile Tornado
In critical sectors where high-stakes situations are common, effective communication is non-negotiable. Whether it’s first responders dealing with a crisis or a construction team coordinating a complex project, the ability to share information quickly and reliably can mean the difference between success and failure.
Long-distance communication became feasible in the 1950s when wireless network connectivity was first utilised in mobile radio-telephone systems, often using push-to-talk (PTT) technology. As private companies invested in cellular infrastructure, the networks developed and data speeds improved increasingly. Each major leap forward in mobile network capabilities was classed as a different generation and thus 1G, 2G, 3G, 4G, and now 5G were born.
5G is the fifth generation of wireless technology and has been gradually rolled out since 2019 when the first commercial 5G network was launched. Since then, the deployment of 5G infrastructure has been steadily increasing, with more and more countries and regions around the world adopting this cutting-edge technology.
Its rollout has been particularly significant for critical sectors that rely heavily on push-to-talk over cellular (PTToC) solutions. With 5G, PTToC communications can be carried out with higher bandwidth and speed, resulting in clearer and more seamless conversations, helping to mitigate risks in difficult scenarios within critical sectors.
How is 5G benefiting businesses?
According to Statista, by 2030, half of all connections worldwide are predicted to use 5G technology, increasing from one-tenth in 2022. This showcases the rapid pace at which 5G is becoming the standard in global communication infrastructure.
But what does this mean for businesses? Two of the key improvements under 5G are improved bandwidth and download speeds, facilitating faster and more reliable communication within teams. PTToC solutions can harness the capabilities of 5G and bring the benefits to critical sectors that need it most, whether that’s in public safety, security, or logistics: the use cases are infinite. For example, this could be leveraging 5G’s increased bandwidth to enable larger group calls and screen sharing for effective communication.
Communication between workers in critical industries can be difficult, as often the workforces are made up of lone workers or small groups of individuals in remote locations. PTToC is indispensable in these scenarios for producing quick and secure communication, as well as additional features including real-time location information and the ability to send SOS alerts. PTToC with 5G works effectively in critical sectors, as 5G is designed to be compatible with various network conditions, including 2G and 3G. This ensures that communication remains reliable and efficient even in countries or areas where 5G infrastructure is not fully deployed to keep remote, lone workers safe and secure.
The impact of 5G on critical communications
The International Telecommunication Union has reported that 95 percent of the world’s population can access a mobile broadband network. This opens up a world of new possibilities for PTToC, particularly when harnessing new capabilities for 5G as it’s being rolled out.
One of the most significant improvements brought by 5G is within video communications, which most PTToC solutions now offer. Faster speeds, higher bandwidth, and lower latency enhance the stability and quality of video calls, which are crucial in critical sectors. After all, in industries like public safety, construction, and logistics, the importance of visual information for effective decision-making and situational awareness cannot be overstated. 5G enables the real-time transmission of high-quality video, allowing for effective coordination and response strategies, ultimately improving operational outcomes and safety measures.
Challenges in Adopting 5G in Critical Sectors
While the benefits of 5G are undeniable, the industry faces some challenges in its widespread adoption. Network coverage and interoperability are two key concerns that need to be addressed to ensure communication can keep improving in critical sectors.
According to the International Telecommunication Union, older-generation networks are being phased out in many countries to allow for collaborative 5G standards development across industries. Yet, particularly in lower-income countries in Sub-Saharan Africa, Latin America, and Asia-Pacific, there is a need for infrastructure upgrades and investment to support 5G connectivity. The potential barriers to adoption, including device accessibility, the expense of deploying the new networks, and regulatory issues, must be carefully navigated to help countries make the most out of 5G capabilities within critical sectors and beyond.
However, the rollout of 5G does cause data security concerns for mission-critical communications and operations, as mobile networks present an expanded attack surface. Nonetheless, IT professionals, including PTToC developers, have the means to safeguard remote and lone workers and shield corporate and employee data. Encryption, authentication, remote access, and offline functionality are vital attributes that tackle emerging data threats both on devices and during transmission. Deploying this multi-tiered strategy alongside regular updates substantially diminishes the vulnerabilities associated with exploiting 5G mobile networks and devices within critical sectors.
While the challenges faced by the industry must be addressed, the potential benefits of 5G in enhancing communication and collaboration are undeniable. As the rollout of 5G continues to gain momentum, the benefits of this cutting-edge technology in enhancing communication in critical sectors are becoming increasingly evident. The faster, more reliable, and efficient communication enabled by 5G is crucial for industries that rely on real-time information exchange and decision-making.
Looking ahead, the potential for further advancements and increased adoption of 5G in critical sectors is truly exciting. As the industry continues to address the challenges faced, such as network coverage, interoperability, and data security concerns, we can expect to see even greater integration of this technology across a wide range of mission-critical applications for critical sectors.

Adapting compliance in a fragmented regulatory world

Rasha Abdel Jalil, Director of Financial Crime & Compliance at Eastnets, discusses the operational and strategic shifts needed to stay ahead of regulatory compliance in 2025 and beyond.
As we move through 2025, financial institutions face an unprecedented wave of regulatory change. From the EU’s Digital Operational Resilience Act (DORA) to the UK’s Basel 3.1 rollout and upcoming PSD3, the volume and velocity of new requirements are constantly reshaping how banks operate.
But it’s not just the sheer number of regulations that’s creating pressure. It’s the fragmentation and unpredictability. Jurisdictions are moving at different speeds, with overlapping deadlines and shifting expectations. Regulators are tightening controls, accelerating timelines and increasing penalties for non-compliance. And for financial compliance teams, it means navigating a landscape where the goalposts are constantly shifting.
Financial institutions must now strike a delicate balance: staying agile enough to respond to rapid regulatory shifts, while making sure their compliance frameworks are robust, scalable and future-ready.
The new regulatory compliance reality
By October of this year, financial institutions will have to navigate a dense cluster of regulatory compliance deadlines, each with its own scope, jurisdictional nuance and operational impact. From updated Common Reporting Standard (CRS) obligations, which applies to over 100 countries around the world, to Australia’s new Prudential Standard (CPS) 230 on operational risk, the scope of change is both global and granular.
Layered on top are sweeping EU regulations like the AI Act and the Instant Payments Regulation, the latter coming into force in October. These frameworks introduce new rules and redefine how institutions must manage data, risk and operational resilience, forcing financial compliance teams to juggle multiple reporting and governance requirements. A notable development is Verification of Payee (VOP), which adds a crucial layer of fraud protection for instant payments. This directly aligns with the regulator’s focus on instant payment security and compliance.
The result is a compliance environment that’s increasingly fragmented and unforgiving. In fact, 75% of compliance decision makers in Europe’s financial services sector agree that regulatory demands on their compliance teams have significantly increased over the past year. To put it simply, many are struggling to keep pace with regulatory change.
But why is it so difficult for teams to adapt?
The answer lies in a perfect storm of structural and operational challenges. In many organisations, compliance data is trapped in silos spread across departments, jurisdictions and legacy platforms. Traditional approaches – built around periodic reviews, static controls and manual processes – are no longer fit for purpose. Yet despite mounting pressure, many teams face internal resistance to changing established ways of working, which further slows progress and reinforces outdated models. Meanwhile, the pace of regulatory change continues to accelerate, customer expectations are rising and geopolitical uncertainty adds further complexity.
At the same time, institutions are facing a growing compliance talent gap. As regulatory expectations become more complex, the skills required to manage them are evolving. Yet many firms are struggling to find and retain professionals with the right mix of legal, technical and operational expertise. Experienced professionals are retiring en-masse, while nearly half of the new entrants lack the right experience needed to step into these roles effectively. And as AI tools become more central to investigative and decision-making processes, the need for technical fluency within compliance teams is growing faster than organisations can upskill. This shortage is leaving compliance teams overstretched, under-resourced and increasingly reliant on outdated tools and processes.
Therefore, in this changing environment, the question suddenly becomes how can institutions adapt?
Staying compliant in a shifting landscape
The pressure to adapt is real, but so is the opportunity. Institutions that reframe compliance as a proactive, technology-driven capability can build a more resilient and responsive foundation that’s now essential to staying ahead of regulatory change.
This begins with real-time visibility. As regulatory timelines change and expectations rise, institutions need systems that can surface compliance risks as they emerge, not weeks or months later. This means adopting tools that provide continuous monitoring, automated alerts and dynamic reporting.
But visibility alone isn’t enough. To act on insights effectively, institutions also need interoperability – the ability to unify data from across departments, jurisdictions and platforms. A modern compliance architecture must consolidate inputs from siloed systems into a unified case manager to support cross-regulatory reporting and governance. This not only improves accuracy and efficiency but also allows for faster, more coordinated responses to regulatory change.
To manage growing complexity at scale, many institutions are now turning to AI-powered compliance tools. Traditional rules-based systems often struggle to distinguish between suspicious and benign activity, leading to high false positive rates and operational inefficiencies. AI, by contrast, can learn from historical data to detect subtle anomalies, adapt to evolving fraud tactics and prioritise high-risk alerts with greater precision.
When layered with alert triage capabilities, AI can intelligently suppress low-value alerts and false positives, freeing up human investigators to focus on genuinely suspicious activity. At the more advanced stages, deep learning models can detect behavioural changes and suspicious network clusters, providing a multi-dimensional view of risk that static systems simply can’t match.
Of course, transparency and explainability in AI models are crucial. With regulations like the EU AI Act mandating interpretability in AI-driven decisions, institutions must make sure that every alert or action taken by an AI system is auditable and understandable. This includes clear justifications, visual tools such as link analysis, and detailed logs that support human oversight.
Alongside AI, automation continues to play a key role in modern compliance strategies. Automated sanction screening tools and watchlist screening, for example, help institutions maintain consistency and accuracy across jurisdictions, especially as global lists evolve in response to geopolitical events.
Similarly, customisable regulatory reporting tools, powered by automation, allow compliance teams to adapt to shifting requirements under various frameworks. One example is the upcoming enforcement of ISO 20022, which introduces a global standard for payment messaging. Its structured data format demands upgraded systems and more precise compliance screening, making automation and data interoperability more critical than ever.
This is particularly important in light of the ongoing talent shortages across the sector. With newer entrants still building the necessary expertise, automation and AI can help bridge the gap and allow teams to focus on complex tasks instead.
The future of compliance
As the regulatory compliance landscape becomes more fragmented, compliance can no longer be treated as a tick-box exercise. It must evolve into a dynamic, intelligence-led capability, one that allows institutions to respond to change, manage risk proactively and operate with confidence across jurisdictions.
To achieve this, institutions must rethink how compliance is structured, resourced and embedded into the fabric of financial operations. Those that do, and use the right tools in the process, will be better positioned to meet the demands of regulators today and in the future.

Why Shorter SSL/TLS Certificate Lifespans Are the Perfect Wake-Up Call for CIOs

By Tim Callan, Chief Compliance Officer at Sectigo and Vice-Chair of the CA/Browser Forum
Let’s be honest: AI has been the headline act this year. It’s the rockstar of boardroom conversations and LinkedIn thought leadership. But while AI commands the spotlight, quantum computing is quietly tuning its instruments backstage. And when it steps forward, it won’t be playing backup. For CIOs, the smart move isn’t just watching the main stage — it’s preparing proactively for the moment quantum takes center stage and rewrites the rules of data protection.
Quantum computing is no longer a distant science project. NIST has already published standards for quantum-resistant algorithms and set a clear deadline: RSA and ECC, the cryptographic algorithms that protect today’s data, must be deprecated by 2030. We’re no longer talking about “forecasts;” we are talking about actual directives from government organizations to implement change. And yet, many organizations are still treating this like a future problem. The reality is that threat actors aren’t waiting. They’re collecting encrypted data now, knowing they’ll be able to decrypt it later. If we wait until quantum machines are commercially viable, we’ll be too late. The time to prepare is before the clock runs out and, unfortunately, that clock is already ticking.
For CIOs, this is an infrastructure and risk management crisis in the making. If your organization’s cryptographic infrastructure isn’t agile enough to adapt, the integrity of your digital operations and the trust they rely on could very soon be compromised.
The Quantum Threat Is Already Here
Quantum computing’s potential to disrupt global systems and the data that runs through it is not hypothetical. Attackers are already engaging in “Harvest Now, Decrypt Later” (HNDL) strategies, intercepting encrypted data today with the intent to decrypt it once quantum capabilities mature.
Recent research found that an alarming 60% of organizations are very or extremely concerned about HNDL attacks, and 59% express similar concern about “Trust Now, Forge Later” threats, where adversaries steal digitally signed documents to forge them in the future.
Despite this awareness, only 14% of organizations have conducted a full assessment of systems vulnerable to quantum attacks. Nearly half (43%) of organizations are still in a “wait and see” mode. For CIOs, this gap highlights the need for leadership: it’s not
enough to know the risks exist, you must identify which systems, applications, and data flows will still be sensitive in ten or twenty years and prioritize them for PQC migration.
Crypto Agility Is a Data Leadership Imperative
Crypto agility (the ability to rapidly identify, manage, and replace cryptographic assets) is now a core competency for IT leaders to ensure business continuity, compliance, and trust. The most immediate pressure point is SSL/TLS certificates. These certificates authenticate digital identities and secure communications across data pipelines, APIs, and partner integrations.
The CA/Browser Forum has mandated a phased reduction in certificate lifespans from 398 days today to just 47 days by 2029. The first milestone arrives in March 2026, when certificates must be renewed every six months, shrinking to near-monthly by 2029.
For CIOs, it’s not just an operational housekeeping issue. Every expired or mismanaged certificate is a potential data outage. That means application downtimes, broken integration, failed transactions and compliance violations. With less than 1 in 5 organizations prepared for monthly renewals, and only 5% fully automating their certificate management processes currently, most enterprises face serious continuity and trust risks.
The upside? Preparing for shortened certificate lifespans directly supports quantum readiness. Ninety percent of organizations recognize the overlap between certificate agility and post-quantum cryptography preparedness. By investing in automation now, CIOs can ensure uninterrupted operations today while laying a scalable foundation for future-proof cryptographic governance.
The Strategic Imperative of PQC Migration
Migrating to quantum-safe algorithms is not a plug-and-play upgrade. It’s a full-scale transformation. Ninety-eight percent of organizations expect challenges, with top barriers including system complexity, lack of expertise, and cross-team coordination. Legacy systems (many with hardcoded cryptographic functions) make this even harder.
That’s why establishing a Center of Cryptographic Excellence (CryptoCOE) is a critical first step. A CryptoCOE centralizes governance, aligns stakeholders, and drives execution. According to Gartner, by 2028 organizations with a CryptoCOE will save 50% of costs in their PQC transition compared to those without.
For CIOs, this is a natural extension of your role. Cryptography touches every layer of enterprise infrastructure. A CryptoCOE ensures that cryptographic decisions are made with full visibility into system dependencies, risk profiles and regulatory obligations.
By championing crypto agility as an infrastructure priority, CIOs can transform PQC migration from a technical project into a strategic initiative that protects the organization’s most critical assets.
The Road Ahead
The shift to 47-day certificates is a wake-up call. It marks the end of static cryptography and the beginning of a dynamic, agile era. Organizations that embrace this change will not only avoid outages and compliance failures, but they’ll be also prepared for the quantum future.
Crypto agility is both a technical capability and a leadership mandate. For CIOs, the path forward to quantum-resistant infrastructure can be clear: invest in automation, build cross-functional alignment, and treat cryptographic governance as a core pillar of enterprise resilience.

The Security Talent Gap is a Red Herring: It’s Really an Automation and Context Gap

by Tom Gol, Senior Product Manager Armis
We constantly hear about a cybersecurity staffing crisis, but perhaps the real challenge isn’t a lack of people. It might just be a critical shortage of intelligent automation and actionable context for the talented teams we already have.
The Lingering Shadow of the “Talent Gap” Narrative
It’s almost a mantra in cybersecurity circles: “There’s a massive talent gap!” Conferences echo it, reports reinforce it, and CISOs often feel it acutely. This widely accepted idea suggests we simply don’t have enough skilled professionals, leading to overworked teams, burnout, and, most critically, persistent organizational risk. The default response often becomes a relentless cycle of “buy more tools, tune more tools, and staff more teams”—a cycle that feels increasingly unsustainable and inefficient.
But what if this pervasive “talent gap” is actually a clever red herring, distracting us from a more fundamental issue? We’ve grown so accustomed to the narrative of a human deficit that we often overlook a crucial truth: current technology is already capable of significantly narrowing this very gap. My strong conviction is this: the true underlying problem isn’t a shortage of available talent, but a profound and crippling gap in intelligent automation and actionable context that prevents our existing cybersecurity professionals from operating at their full potential. What’s more, advancing on the technology side now presents a demonstrably better return on investment than simply trying to out-hire the problem. Fill that gap with smarter tech, and watch the perceived talent shortage shrink.
Misdiagnosis: When More People Isn’t the Answer
For too long, the cybersecurity industry’s knee-jerk reaction to mounting threats has been to throw more human resources at the problem. Yet, the attack surface continues its relentless expansion. Threat actors become more sophisticated. And our SOCs are constantly drowning in an unfiltered deluge of alerts. This creates an overwhelming workload that even the most seasoned experts find impossible to manage effectively, often resulting in burnout and, ironically, talent attrition rather than retention.
The issue isn’t that a lack of bright minds are joining the field. It’s that those brilliant minds often find themselves mired in monotonous, low-value tasks. They’re forced to operate in a thick fog of incomplete information, constantly sifting through noise. When security teams lack clarity on exactly what assets they own, how those assets connect, what their true business criticality is, and which threats are genuinely active, even the most experienced professional struggles. Their effectiveness diminishes, not from a lack of inherent skill, but from a fundamental absence of visibility and intelligent support.
Automation and AI: The True Force Multiplier for Human Talent
The real power move against the overwhelming tide of cyber threats lies not in endless recruitment, but in the intelligent application of automation and AI. Leading industry discussions increasingly highlight that the purpose of AI in cybersecurity isn’t about wholesale human replacement. Instead, it’s about augmenting our existing staff, turning them into a far more potent force. This approach fundamentally allows organizations to scale their expertise and impact without being shackled to proportional headcount increases. Let’s unpack how this transformation plays out.
Freeing Up Human Capital from the Mundane
Imagine a security analyst whose day is consumed by hours of manual investigation, enriching alerts, triaging false positives, responding to routine questionnaires, or laboriously transitioning tickets. These are precisely the kinds of non-human, deterministic, and highly repetitive tasks ripe for intelligent automation. AI agents can seamlessly take on this soul-crushing burden, liberating human analysts. They are then free to pivot towards higher-value, creative, judgment-based, and genuinely strategic work. This transforms security teams from reactive task-runners into proactive problem-solvers. Projections suggest that common SOC tasks could become significantly more cost-efficient in the coming years due to automation—a shift that’s not merely about saving money, but about amplifying human potential.
Supercharging Productivity and Experience
Modern AI, particularly multi-agent AI and generative AI, can proactively offer smart advice on configurations, predict the root causes of complex issues, and integrate effortlessly with existing automated frameworks. This empowers security professionals, making their work not just more efficient but also more engaging and less prone to drudgery.
The Indispensable Power of Context: Lowering the “Expertise Bar”
While automation tackles the sheer volume of work, context provides the vital clarity that fundamentally reduces the need for constant, deep-seated expertise in every single scenario. When security professionals have immediate, rich, and actionable context about a vulnerability or an emerging threat, the path to intelligent prioritization and decisive action becomes remarkably clearer.
Consider the profound difference this context makes:
- Asset Context: Knowing not just that a vulnerability exists, but precisely which specific device it resides on—is it a critical production server, or an isolated, deprecated test machine?
- Business Application Context: Understanding the exact business function tied to that asset, and the tangible financial or operational impact if it were to be compromised.
- Network Context: Seeing the asset’s intricate network connections, its precise exposure level, and every potential path an attacker could take for lateral movement.
- Compensating Controls Context: Having a clear, real-time picture of which existing security controls (like network segmentation, EDRs, or Intrusion Prevention Systems) are actually in place and effectively working to mitigate the vulnerability’s risk.
- Threat Intelligence Context: Possessing real-time, “active exploit” intelligence that doesn’t just theorize, but tells you if a vulnerability is actively being exploited in the wild, or is part of a known attack campaign targeting your industry.
With this deep, multidimensional context, a significant portion of the exposure management workload can be automated. Crucially, for the tasks that still require human intervention, the “expertise bar” is dramatically lowered. My take is that for a vast majority of cases—perhaps 90% of scenarios—a security professional who isn’t a battle-hardened, 20-year veteran can still make incredibly effective decisions and significantly improve an organization’s cyber posture. This is because they are presented with clear, actionable context that naturally guides prioritization and even recommends precise actions. The result? A drastic reduction in alert noise, faster detection and response times, and a palpable easing of the burden on the entire security team.
Navigating the Human Element: Skills Evolution and Burnout
This powerful shift towards automation and AI naturally brings legitimate questions about skills erosion. Some experts prudently point out a valid risk: a significant portion of SOC teams might experience a regression in foundational analysis skills due to an over-reliance on automation. This underscores a critical truth: we must keep humans firmly in the loop. For highly autonomous SOCs, a “human-on-the-loop” approach is recommended, reserving human intervention for complex edge cases and critical exceptions.
CISOs, therefore, face an evolving mandate:
- Future-Proofing Skills: It’s less about filling historical roles and more about nurturing new competencies like prompt engineering, sophisticated AI oversight, advanced critical thinking, and strategic problem-solving.
- Combating Burnout: Beyond just tools, effective talent retention demands proactive measures to address burnout. This includes intelligent workload monitoring, smart task delegation, and genuine wellness initiatives. The ultimate goal isn’t just to fill empty seats; it’s to ensure that the people in those seats are effective, sustainable, and thriving.
A New Mindset for CISOs: Embracing the “Chief Innovation Security Officer” Role
The ongoing “talent gap” discussion should be a catalyst for CISOs to adopt a fundamentally new mindset. Instead of simply focusing on cost-cutting or the perpetual struggle of recruitment, they must evolve into “Chief Innovation Security Officers.” This means daring to rethink how work gets done, leveraging AI and automation not merely as tactical tools but as strategic enablers for scaling cybersecurity capabilities and unlocking the full potential of their existing talent. This strategic investment in technology, driven by an understanding of context, offers a superior ROI in bridging the cybersecurity “gap” compared to the increasingly futile effort to simply hire more people.
Building robust AI governance frameworks and achieving crystal-clear visibility into existing AI implementations and technical debt are crucial foundational steps. Ultimately, solving the perceived talent gap isn’t about endlessly hiring more people into an unsustainable system. It’s about empowering the talented individuals we do have—making them more efficient, more effective, and more strategically focused—through the intelligent application of automation and unparalleled context. It’s time to stop chasing a phantom gap and start truly empowering our digital defenders.
