Compare cybersecurity audit quotes in Edinburgh
Edinburgh's financial services concentration - asset management, insurance, and banking - means many buyers face regulatory security requirements from the FCA and PRA, as well as Scottish Government contract requirements that specify CHECK-accredited penetration testers. Edinburgh-based CREST-accredited firms are fewer in number than in London, and buyers should expect to brief firms across Scotland and the wider UK rather than limiting the search to those with an Edinburgh office. The quality difference between a strong CREST-accredited specialist and a general IT firm offering security testing as an add-on is significant.
If you are looking for the best security firms in Edinburgh, the most reliable shortlist is one built around your own requirements and tested with a structured brief - not a generic ranked list. RFXapp helps you find and collect quotes from the right suppliers, and analyse them so you can compare what they actually offer, not just the headline price.
What to consider before you go to market
Getting comparable quotes starts with a well-scoped brief. These are the things most businesses overlook until they're already in the process.
Audit type: penetration test vs vulnerability assessment vs Cyber Essentials
These are distinct services that are often conflated. A vulnerability assessment is an automated scan of your systems to identify known weaknesses. A penetration test uses human testers who actively exploit vulnerabilities to determine what a real attacker could access. Cyber Essentials is a UK government-backed certification required for public sector contracts - Scottish Government contracts require Cyber Essentials as a minimum, and many specify Cyber Essentials Plus. Know which you need before going to market. An Edinburgh financial services firm under FCA scrutiny has different requirements from a Scottish Government supplier, and conflating the two wastes both time and budget.
CREST and CHECK accreditation - particularly relevant for Scottish Government work
For penetration testing, CREST accreditation is the UK industry standard. CHECK accreditation - required for testing UK government systems - is particularly relevant in Edinburgh given the concentration of Scottish Government and public sector work. CHECK is a stronger credential than CREST alone, and Edinburgh firms tendering for Scottish Government contracts should confirm the security firm holds CHECK accreditation, not just CREST. Edinburgh has a limited number of locally based accredited firms; verify on the CREST website and do not limit your search geographically.
Scope definition: what is in and what is out
A penetration test can cover external infrastructure, internal network, web applications, cloud environments, or any combination. For Edinburgh financial services firms, the scope needs to address the systems that hold or process client financial data - which in 2025 typically means cloud platforms (Microsoft 365, Azure) and any client-facing web applications. An external-only test of your corporate website will not satisfy FCA risk assessment requirements if your client portal and trading systems are out of scope. Define scope against your regulatory and commercial requirements before briefing.
Report quality: executive summary vs technical findings
For Edinburgh financial services firms, audit reports often need to satisfy multiple audiences: a technical IT team, a risk committee, and sometimes the FCA or an institutional investor conducting due diligence. A report that only produces a technical appendix without a clear executive summary and risk-prioritised finding list will not travel well through your organisation. Ask to see a redacted example report before selecting a firm, and confirm the format can be adapted for a board or regulator audience if required.
Remediation support: included or separate
Finding vulnerabilities is only half the job. Acting on them is the other half. Some security firms include a remediation consultation in the audit price; others treat it as a separate engagement priced after seeing the findings. For FCA-regulated Edinburgh firms where the audit forms part of an annual risk management cycle, the remediation phase needs to fit the same timeline. Establish upfront whether remediation support is included and at what rate, so the full cost of the engagement is known before you start.
Retest policy for critical findings
After a penetration test, your team fixes the vulnerabilities identified. A retest confirms the fixes are effective. Whether the retest is included in the initial price or charged at full day rate makes a material difference to total engagement cost. For Edinburgh financial services firms where audit outcomes are reported to a risk committee or the FCA, a completed retest is often required to demonstrate that findings have been closed. Pre-agree retest terms before the initial test starts.
Hidden costs and oversights that catch Edinburgh businesses out
These are the items that make two cybersecurity audit quotes look comparable on paper but leave your real attack surface untested or your regulatory requirement unmet.
Scope that excludes cloud assets and remote worker endpoints
Edinburgh financial services firms have significant data in cloud platforms - client records, trading data, and communications typically sit in Microsoft 365 and cloud-hosted applications. Standard pentest scopes frequently exclude these. A test that covers only on-premise infrastructure produces a false assurance that does not reflect where the real risk is. For FCA-regulated firms, this gap can also undermine the credibility of the audit if it is reviewed as part of a regulatory assessment.
Firms that classify all findings as high severity to inflate remediation scope
Severity inflation is a common tactic - producing a report where every finding is "Critical" or "High" makes the risk look alarming and drives remediation engagements. Edinburgh financial services firms, where risk committees are primed to escalate security findings, are a particularly susceptible audience. Before selecting a firm, ask how they calibrate severity and ask to see a previous (redacted) report. A properly calibrated report will include Low and Informational findings alongside any genuine critical issues.
No retest included: paying full day rate to verify your own fixes
A penetration test without a pre-agreed retest means your team fixes the vulnerability but can only confirm the fix worked by commissioning another engagement at full rate. For a five-day pentest at £8,000-£15,000, a retest of critical findings can add £3,000-£7,000 if not pre-agreed. For Edinburgh financial services firms where findings are tracked through a risk register and need to be formally closed, an unbudgeted retest cost is a common source of programme overrun. Negotiate retest terms before signing.
Questions that separate good security firms from great ones
Asking is only half the job. Below each question is what a good answer sounds like, and what should give you pause. Questions marked * are mainly relevant for larger or more complex engagements - for a straightforward Cyber Essentials certification or single-scope assessment you can skip those.
Good answer: They name the specific tester, confirm their CREST or CHECK certification level, and offer documentation. For CHECK-accredited work, they can confirm the individual holds the relevant CHECK tier for your system type.
Red flag: "Our team is CREST-accredited" without identifying the individual. That is firm-level accreditation only and does not confirm who will run your test.
Good answer: A specific answer naming which cloud platforms are in scope, how remote endpoints are addressed, and clear identification of any out-of-scope items. A firm experienced with financial services clients can answer this without hesitation.
Red flag: "We cover your infrastructure" without specifying cloud or remote assets. Almost always means those assets are out of scope.
Good answer: They provide a sample promptly, ideally from a financial services engagement. The sample shows clear severity ratings with justification, an executive summary suitable for a risk committee, and technical findings for the IT team.
Red flag: "We can't share client reports due to confidentiality." A properly redacted sample removes all identifying information - this is not a valid reason to refuse.
Good answer: They confirm whether remediation review sessions are included or provide a pre-agreed fixed rate. Either is acceptable; what matters is that it is agreed before the test starts.
Red flag: "We'll scope remediation once we've seen the findings." That means pricing at the moment of maximum leverage.
Good answer: A specific pre-agreed retest policy - one retest of critical and high findings within 90 days of the initial report, included or at a fixed pre-agreed rate.
Red flag: "We'll discuss retest pricing after the report is delivered." That is the moment when you have least leverage.
Good answer: A clear explanation referencing CVSS, OWASP, or NCSC guidance. The firm should be comfortable explaining that not every engagement produces critical findings.
Red flag: A vague answer without methodology reference, or any suggestion that every engagement produces critical findings.
Where you have more negotiating room than you think
Security firms have more flexibility on price and terms than they lead with. These are the levers that actually work once you have competing quotes in front of you.
Bundle Cyber Essentials Plus with a penetration test
Edinburgh businesses needing both Cyber Essentials Plus (for Scottish Government or public sector contracts) and a penetration test (for FCA risk management or client assurance) can often save 10-20% by commissioning both from the same firm in a single engagement. Some firms also discount the annual Cyber Essentials renewal when combined with an ongoing penetration testing relationship.
Annual contract for quarterly vulnerability scanning plus an annual pentest
One-off penetration tests are priced as discrete engagements. An annual contract - quarterly automated vulnerability scanning plus one full pentest per year - changes the firm's pricing model and fits naturally into the annual risk management cycle that most Edinburgh financial services firms already operate. The recurring revenue changes what the firm is willing to charge for the initial engagement.
Phase the test: external and cloud first, internal second
A phased approach - Phase 1 covering external infrastructure and cloud environments, Phase 2 covering internal trading and operational systems - lets you assess the firm's work quality before providing access to sensitive internal systems. For Edinburgh financial services firms, where internal systems hold client data and trading records, the phased approach is also a sensible risk management structure.
Pre-agree the retest scope and price before the initial test
Once you have the findings report and a risk committee expecting to see findings formally closed, the security firm has significant leverage on retest pricing. Pre-agreeing retest scope and day rate before the initial test removes this entirely and allows you to build a realistic risk closure timeline into your governance reporting.
Competitive quotes from two CREST-accredited firms
Edinburgh has a smaller local market than London but the UK-wide CREST-accredited security market is large enough that meaningful price variation exists. Running a structured RFQ process with two or three accredited firms - including those based in Glasgow, Edinburgh, or elsewhere in the UK who can deliver remotely - produces real competitive tension and prevents single-supplier pricing.
Timing: security firms have quieter periods in summer and over Christmas
Penetration testing firms have quieter periods in July to September and over Christmas when tester availability is high. Testing at these times often produces better scheduling and sometimes a pricing concession. For Edinburgh firms without a hard regulatory deadline tied to a specific calendar date, building in timing flexibility is worth considering.
