Cyber Security Assessment
What is Cyber Security Assessment?
Your strategic plan is also a security plan. Almost nobody reads it that way.
Look at what your firm has committed to over the next three years. A core platform migration, a savings app that members will actually use, broker channel growth, a merger, or the capacity to absorb one, cost to income targets that depend on automating work people do today. Every one of those changes the shape of your attack surface, and every one was approved on a business case that priced the delivery and not the exposure.
Meanwhile the control environment underneath is doing its own drifting. Controls bought for a problem that has moved on. Configurations changed under project pressure. Assumptions that were sound when the estate sat in one data centre.
A Cyber Security Assessment answers two questions at once. Where does the security posture actually stand today, and does it hold for the firm you are in the middle of becoming? Measured against NIST CSF, ISO 27001 or CIS Controls, against the threat your sector is currently seeing, and against your own change portfolio.
For PRA regulated firms it is also the work behind a defensible CQUEST return and a board that can answer questions without reaching for the CISO.
The challenges
Change approved without the security cost attached: Programme business cases carry delivery cost, benefit and timeline. They rarely carry the control uplift the new architecture will need, so the requirement surfaces late, competes with go live, and loses.
Controls sized for the firm you were: Security estates accumulate rather than adapt. Tooling procured for a specific problem, configured at pace, then left. Nobody decides to let a control drift. It happens because nothing routinely checks.
Cyber running alongside operational resilience instead of inside it: Since PS21/3 you have had to show that severe but plausible scenarios stay within impact tolerance for important business services. Cyber is the most likely of those scenarios. An assessment that stops at control maturity does not answer the question your supervisor is asking.
Nobody inside can mark their own homework: Internal teams built the controls, granted the exceptions and know the reason for every one. That knowledge is valuable and it is exactly why internal assessment struggles to be objective. Boards and supervisors read it accordingly.
Too many findings, not enough hands: A four person risk function handed 120 findings has been given a problem, not an answer. Without prioritisation that reflects real business consequence, the list becomes a backlog and the backlog becomes evidence of inaction.
How to solve it
We start from the strategy, not the framework: Before the control review, we read the corporate plan, the change portfolio and the board pack. The assessment is then scoped around what the firm is trying to do, so the findings speak to the projects that are already funded.
We baseline honestly: Policies, procedures and technical controls against NIST CSF, ISO 27001 or CIS Controls, whichever fits. The starting point is where you actually are, not where the last report said.
We work back from important business services: From the services members depend on, through the systems and suppliers that deliver them, to the controls that protect them. That connects the assessment to your operational resilience framework rather than running a parallel exercise.
We assess the target state as well as the current one: Where a migration or a new channel is in flight, we assess the architecture being built, not only the one being replaced. Findings raised in design cost a fraction of findings raised after go live.
We give you a roadmap you can fund: Sequenced actions, realistic timelines, and the resource picture behind each. Aligned to the change portfolio so security work rides existing programmes where it can rather than always competing with them.
We stay for the delivery: Support to turn findings into change across controls, policy and training. The assessment starts the work rather than concluding it.
The benefits of our services
We work almost entirely with building societies, mutual lenders and specialist insurers, which means we understand the constraint you are actually operating under: an ambitious plan, a small team, and a legacy estate that is not going anywhere this year.
Independence that survives scrutiny: An external assessment carries weight with boards, audit committees and supervisors that an internal one does not, because the team producing it has no stake in the answer.
Proportionate by design: We do not apply a tier one bank methodology to a two billion pound balance sheet. The assessment scales to the firm and so does the roadmap.
Findings that turn into change: The value of an assessment is not the document. It is what moves afterwards. That is what we measure ourselves on.
