Certification Is the Beginning, Not the End of Your Security Journey

Security certifications play a vital role for organisations. They help companies prove maturity, streamline regulatory compliance and even open up new business opportunities. However, the true value of standards like ISO 27001 and ISO 27701 is only realised when they are approached as more than a compliance exercise. Too often, organisations focus solely on achieving certification quickly, treating it as a “one-and-done” effort rather than an ongoing commitment.

Certification is certainly a milestone moment to celebrate on the journey to resilience. But it’s not the finish line, because business resilience is something you sustain and strengthen over time, not a one-off achievement.

Beyond the badge

With so much emphasis on how quickly certification can be achieved, organisations risk confusing rapid certification with genuine resilience. IO’s latest research revealed that 87% of cybersecurity managers in the UK believe the speed at which compliance certifications are achieved undermines their credibility. 

A further 21% believe that third-party certifications quickly become outdated post audit. Could it be that organisations are so focused on achieving certification that they overlook what comes next?

The truth is that point-in-time compliance can't keep pace with today's threats or the speed at which AI is reshaping them. It encourages reactive security rather than proactive resilience. 

Worse still, when certification becomes a race, the ongoing governance that should follow it can quietly fall away. Letting that oversight lapse once the audit is passed is what erodes resilience over time. Instead, organisations must treat governance and oversight not as a tick-box exercise but an evolving, iterative and business-critical undertaking that constantly adapts as threats and regulations evolve.

Best practices in action

Threat actors are continuously probing for gaps in security posture. Using AI and automated tooling, they can do this far quicker and more easily than before. That's why reviewing your resilience can't be a once-a-year exercise. Businesses need to understand how security controls (the safeguards and measures they put into place to reduce risks) are monitored and improved over time, what evidence is needed to do so, who is responsible for maintaining them as well as where humans sit in the process.

From a cyber resilience perspective, continuous oversight requires identifying which controls are most important and defining key metrics. Not every control needs the same level of attention. Organisations should monitor the most business-critical assets and highest-consequence risks most actively. They must define what ‘good’ looks like for each, set the metrics and automate evidence collection where possible. This frees up human experts for when they’re really needed.

Next, businesses should not treat the review cadence as a separate activity. A monthly review of access controls sits naturally alongside an HR process. When governance is embedded in how the business runs, it stops being an event and becomes a habit.

Third, assign clear ownership. The most common reason ongoing governance falls apart is that nobody is responsible for it between audit cycles. Named accountability at all levels, including senior leadership, is key.

The organisations doing this well have stopped treating governance as something that gets activated before an audit and de-prioritised after it.

The importance of human oversight

Nearly half (45%) of UK security leaders believe human expertise is still essential when evaluating whether compliance processes and actions are relevant or accurate. A third say human oversight is required to interpret complex regulations, and a similar percentage agree that human expertise can challenge the credibility or completeness of automated compliance evidence. They’re right on all counts.

While automation speeds up evidence gathering and routine checks, it simply cannot replace professional, human judgement. This is particularly true when understanding regulatory requirements, identifying where documented compliance posture may not fully reflect operational resilience or assessing context.

Experienced staff play an important role in identifying potential compliance gaps, interpreting ambiguity, assessing operational impact and ensuring that compliance activities align with regulatory obligations and wider business objectives.

Building for resilience

Businesses must start these efforts now. The Cyber Security and Resilience Bill will soon become law, enacting some of the most significant updates to UK cyber legislation since the NIS Regulations of 2018. It doesn’t apply to all businesses, but there are lessons for every organisation.

Those that have already achieved ISO 27001 or ISO 27701 certification are starting from a position of strength. The governance frameworks, risk management practices and security controls established through these standards closely align with many of the capabilities expected under the Bill. In particular, organisations with mature governance processes are likely to be better equipped to address obligations relating to incident reporting, third-party risk oversight and executive accountability.

However, certification alone is not enough. Regulations and standards establish a baseline for good practice. The organisations that stay ahead are those that continually assess and strengthen their security posture as risks evolve. When continuous improvement becomes embedded in everyday decision-making and operational processes, cybersecurity shifts from a compliance exercise to an organisational capability. That's what enables businesses to maintain trust, adapt to new threats and remain resilient long-term.
