The CIA triad: the foundation of cybersecurity

In the world of cybersecurity, few ideas or concepts are as fundamental and enduring as the CIA triad. Standing for Confidentiality, Integrity, and Availability, the triad has helped shaped information security for decades. It serves as a universal framework for not only technical professionals, but also for policymakers, auditors, business leaders, and executives who want to ensure that systems are secure, resilient, and compliant.

The role of external penetration tests in cybersecurity compliance

Unlike vulnerability scans, which identify known weaknesses, penetration tests actively attempt to exploit vulnerabilities, misconfigurations, and gaps in your defences, mimicking the tactics used by cyber criminals and other threat actors.

What is ‘zero trust’ and how does it relate to compliance?

Zero Trust is a cybersecurity approach built on one core assumption, “Never trust, always verify.” It operates on the principle that no user, device, or system, either internal or external, should be inherently trusted to access resources.

Is there ever a ‘right time’ to start cybersecurity compliance?

The cost of delaying cybersecurity compliance isn’t always visible right away. But it compounds quietly in the background, and when the impact hits, it’s often expensive and time-sensitive.

Understanding the human role in compliance

Businesses often won’t fail audits because they’re ignoring best practices. They fail because people make mistakes, forget things, work with incomplete information, or don’t fully understand what’s being asked of them. Compliance is full of good intentions, but easily undermined by day-to-day mistakes.

Why has compliance become so dreaded?

Whether it’s facing an annual audit, navigating client security questionnaires, or being asked to demonstrate adherence to standards like ISO 27001, SOC 2, or Cyber Essentials, compliance often feels more like a punishment than a protective measure.
