Multi-Layered Cybersecurity: What Every Business Needs to Know

Cybersecurity is no longer just an IT concern—it’s a Board-level priority for every UK business. In 2024, the UK Government’s Cyber Security Breaches Survey reported that half of UK businesses identified a cyberattack or breach in the previous 12 months, with the average cost for medium and large businesses hitting nearly £20,000 per incident. The real threat, however, goes beyond financial loss: downtime, reputational damage, and even legal repercussions can all follow a successful breach.

The landscape of threats has changed significantly in recent years. Today, businesses are facing sophisticated phishing campaigns, targeted ransomware attacks, and exploitation of software vulnerabilities at an unprecedented scale. Relying on a single line of defence—like antivirus software alone—is no longer enough. Instead, modern best practice calls for a “defence-in-depth” approach, with multiple layers covering your people, processes, and technology.⁠⁠

At Clyk, we use a triple-layered methodology for cybersecurity. First, we implement enterprise-grade security tools, such as advanced firewalls, endpoint protection, and robust spam and malware filtering. Secondly, we enforce multi-factor authentication (MFA) across all key business apps and platforms. Microsoft estimates that MFA alone can prevent over 99.9% of automated account attacks. Thirdly, we believe staff training is non-negotiable: regular workshops and phishing simulations help build a “human firewall,” empowering everyone in your company to spot scams and suspicious activity before problems start⁠⁠.

The process doesn’t end there. True cyber resilience also means maintaining up-to-date documentation, clear escalation procedures, and regular security assessments. This ensures if an incident occurs, the response is swift, confident, and compliant with regulations. We also take ticket prioritisation seriously: a critical security alert always comes first, and regular systems reviews help spot weaknesses before attackers can exploit them⁠⁠.

Finally, regular testing and backup routines are essential for closing the circle. Datto’s latest industry report confirms that UK companies that test backups monthly and combine local and cloud-based backup solutions recover four times faster after attacks than those who do not. At Clyk, we schedule monthly restoration checks, use incremental backup snapshots, and follow strict best practices to make sure your business never loses ground—even if the worst happens⁠⁠.

The message is clear: multi-layered cybersecurity isn’t just about technology, but vigilance, culture, and process. By combining people, process, and product, Clyk shields your business against evolving threats and helps turn security from a source of stress into a true business enabler.
