Endpoint security: Protecting your devices from cyber threats
Blog|by Leanne Bevan|13 October 2025
In today’s hybrid work world, your devices – laptops, smartphones, desktops – are more than just tools. They’re gateways to your business. And that makes them prime targets for cyber criminals.
Endpoint security is the fifth layer of security (see the other layers here). Think of it as the armour that protects these individual devices from threats. It’s not just antivirus anymore. It’s part of a multi-layered strategy that keeps your business safe, responsive and resilient.
Why your endpoints matter
Endpoints are often one the weakest links in your security chain. They’re mobile, personal, and constantly connected. That makes them vulnerable – and attackers know it. In fact, 68% of corporate endpoints are hit by data breach attacks.
Whether it’s a phishing email, a rogue USB stick or an unpatched app, endpoints are where many attacks begin. That’s why securing them is critical.
For instance, Trello had a huge data leak in 2024 due to an API endpoint that did not have proper authentication in place.
Smart tools for strong protection
Here’s how modern endpoint security works in practice:
Antivirus and EDR (Endpoint Detection and Response)
EDR goes far beyond traditional antivirus. It spots suspicious behaviour – like odd process launches or strange network activity – and acts fast. It investigates, isolates the device, and rolls back malicious changes before the threat spreads.
With real-time visibility and automated response, EDR helps you contain threats quickly, reduce downtime, and keep your business running. It also gives your security team the data they need to hunt for stealthy attacks and stay compliant.
Ultimately, EDR helps maintain business continuity by stopping attacks before they escalate, providing forensic data for incident analysis, and supporting compliance efforts.
Managed Detection and Response (MDR)
Don’t have a 24/7 security team? With MDR, you do. Experts monitor your EDR round the clock, saving you time, reducing costs and giving you peace of mind.
MDR is your outsourced Security Operations Centre (SOC), monitoring your EDR tools 24/7. It’s ideal for small and medium-sized businesses that need expert support without the overhead.
MDR analysts proactively search for threats, investigate suspicious activity, and contain incidents before they escalate. You’ll get regular reports, health checks, and peace of mind – knowing someone’s always watching your back.
The combination of technology and human expertise means that threats are detected and remediated swiftly, giving business leaders peace of mind and allowing them to focus on their core operations.
Mobile Device Management (MDM)
Hybrid work means employees use a mix of personal and company devices. MDM keeps them secure.
It enforces security policies on smartphones and tablets, automates updates, and ensures compliance with regulations like GDPR. Lost device? MDM can wipe it remotely. BYOD policy? MDM makes it safe.
With centralised control, IT teams can monitor, update, and protect mobile endpoints – without slowing anyone down.
This flexibility is crucial for organisations embracing bring-your-own-device (BYOD) policies, as it enables secure remote and hybrid work without compromising on protection.
USB port control
USB sticks are still a common attack vector. You might be thinking they’re not used anymore as everything is online, but interestingly USB threats are on the rise again – from surprise “gifts” with hidden malware, to compromised USB sticks used for presentations.
USB port control stops them in their tracks.
By restricting access to USB ports, you prevent data theft and malware infections. You can allow only approved devices, enable read-only access, and log all activity for audits and investigations.
It’s a simple but powerful way to reduce insider threats and strengthen your security posture. Or even prevent USB use altogether.
