Why Endpoint Protection Alone Isn’t Enough in 2025
For many small and medium-sized businesses (SMBs) in the UK, investing in endpoint protection; antivirus, host intrusion prevention, device management, still feels like the “core” cybersecurity decision. After all, nearly every malware campaign starts with a device. But in today’s threat environment, endpoint protection alone is no longer sufficient. Attackers routinely bypass devices, exploit identity and cloud layers, and move laterally once inside. In 2025 the defence perimeter is not just the endpoint, it is identity, device posture, network context and continuous verification. Why Endpoint Protection Alone Falls Short 1. Endpoints are only one piece of the attack surface Endpoint protection focuses on devices like desktops, laptops, mobile devices. Yet attacks increasingly exploit other vectors: cloud apps, identity credentials, remote access, lateral movement inside the network, IoT devices and unmanaged devices. For example, an industry test by SE Labs showed that many “endpoint protection” products for SMBs were challenged by real-world attack simulations of sophisticated adversaries. 2. Identity is the new perimeter While devices matter, identity matters more. If user credentials are compromised, a device may pass endpoint checks but still allow an attacker into critical systems. A 2024 CyberArk report found that 79% of cybersecurity professionals said identity management is the most critical principle for Zero Trust initiatives. 3. Traditional endpoint defences cannot prevent lateral movement Even if the device is protected, once inside the network attackers often move laterally and escalate privileges. Traditional endpoint security often fails to prevent or detect this. One security commentary noted: “Endpoint protection solutions are not enough to protect against human error or insider threats.” 4. The threat environment has changed The growth of remote/hybrid work, BYOD, cloud services and edge computing means endpoints are no longer located purely inside a corporate network. Microsoft’s guidance on Zero Trust shows that endpoint security must be enforced regardless of network location, cloud or home WiFi. What a Modern Security Strategy Must Include Layered security: endpoint plus identity plus network plus cloud Think of endpoint protection as the first line, not the only line. To protect today you also need: Zero Trust as the strategic framework “Never trust, always verify” is the mantra of Zero Trust. According to research, organisations using Zero Trust frameworks reported reduced security incidents: one study found 83% of organisations saw fewer incidents. For SMBs, Zero Trust means verifying identity, device health, user behaviour, application context, not simply trusting the device because it is “inside”. Identity-First Protection Identity rather than device is becoming the primary battleground. For SMBs this means: Why This Matters for UK SMBs Actionable Steps for UK SMBs Step 1: Review your endpoint protection maturity Ask: Do we only protect device breaches? Do we monitor for user credential misuse? Are endpoints always compliant and patched? If yes, good. But also check: does the device trust model assume network location or status? If yes, you have gaps. Step 2: Implement identity and access basics Step 3: Ensure devices meet posture checks Make sure that devices connecting to your network or cloud apps are compliant: OS updates, antivirus, encryption, no jailbroken status, no unmanaged apps. This extends endpoint protection into posture management. Step 4: Introduce network segmentation and monitoring Even with good endpoint and identity controls, if all devices share one flat network you risk lateral spread of threats. Micro-segmentation helps. Real-time monitoring catches abnormal behaviour early. Step 5: Build an incident-ready culture No protection is perfect. Your strategy must assume a breach will happen. Shorter mean-time-to-detect (MTTD) and mean-time-to-respond (MTTR) are critical. Using layered defences reduces blast radius and improves resilience. Key Takeaways At I-Net Software Solutions, we specialise in helping UK SMBs evolve from device-centric protection to identity-first, layered security postures. If you’re relying only on endpoint antimalware and thinking “we’re safe”, it’s time to rethink the strategy. We can help you assess your current controls, identify gaps in identity and access, and build a realistic roadmap for Zero Trust adoption. → Book your Security Readiness Audit Recommended Next Insight How to Fix High Bounce Rates: What Your Visitors Are Actually Telling You From Data to Decisions: A Practical AI Playbook for UK SMBs Managing Remote Work Cyber Risks in 2025
