Cyber Resilience: Readiness Beyond Compliance

While companies invest heavily in cybersecurity, adopting complex policies and ticking boxes, they often remain vulnerable to cyber incidents. Attackers don't check documentation; they test a company's understanding of its IT environment and its ability to react to unusual activity under pressure. This gap highlights the need for cyber resilience, which goes beyond traditional security to encompass a company's capacity to maintain operations, limit damage, and recover quickly after an attack.

In penetration tests, we use similar techniques to attackers, and with the test results, we then upgrade the protocols in the security operations center.

Many organizations struggle with cyber resilience due to a lack of comprehensive insight into their IT infrastructure. Larger companies, in particular, accumulate diverse solutions, applications, servers, and user accounts over time, often managed by internal staff, external contractors, and cloud services. This complexity makes it difficult to understand how systems interact, distinguish normal activity from anomalies, and recognize the early signs of an attack, leading to lost time during critical response phases.

We regularly observe that attackers exploit a sequence of several small consecutive vulnerabilities – from a forgotten account to inadequate rights and access to individual subsystems.

Alen Bezjak, a cybersecurity expert and ethical hacker at A1 Security Operations Center, explains that penetration tests use attacker techniques to enhance security protocols. He notes that attackers often exploit a series of minor vulnerabilities, such as forgotten accounts or improper access rights. The key differentiator for resilient organizations is their ability to detect these event chains promptly. Bezjak emphasizes that his center connects telemetry from the entire environment to identify deviations that individual systems might miss.

The key difference between organizations is precisely in their ability to detect such a chain of events in a timely manner.

Historically, the primary goal was to prevent breaches. Today, the focus has shifted. Experts agree that complete protection is impossible, as attackers leverage automated tools, AI, and increasingly convincing social engineering methods. The ability to survive the "first wave" of an attack now depends on early detection and rapid response, underscoring the importance of understanding and monitoring the entire IT ecosystem.

In the A1 Security Operations Center, we therefore connect telemetry from the entire environment and look for deviations that individual systems do not detect on their own.
