Compare cybersecurity audit quotes in Glasgow
Glasgow has a significant financial services sector alongside a large public sector and NHS presence. Businesses supplying Scottish Government, NHS Scotland, or local authorities face specific security requirements - Scottish Government contracts typically require Cyber Essentials certification, and penetration tests for government systems must be conducted by CHECK-accredited testers. Glasgow buyers should expect to brief firms across Scotland and the UK; the number of locally based CREST-accredited specialists is limited, and the quality variation between a proper specialist and a generalist IT firm offering security testing as a side service is substantial.
If you are looking for the best security firms in Glasgow, 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 Plus is a UK government-backed certification with independent verification - required for Scottish Government and public sector contracts. Know which you need before going to market. A Glasgow business supplying the Scottish Government may need Cyber Essentials Plus as a contract condition, plus a separate penetration test as part of their wider security posture. These are two different engagements with different outputs.
CREST and CHECK accreditation - essential for Scottish Government and NHS work
For penetration testing, CREST accreditation is the UK industry standard. CHECK accreditation is required for penetration tests of UK and Scottish Government systems and is a stronger credential than CREST alone. Glasgow businesses holding or tendering for public sector contracts must confirm the security firm holds CHECK accreditation - and that the individual tester, not just the firm, is CHECK-accredited. Verify on the CREST website. With a limited number of locally based accredited firms in Glasgow, do not restrict your search to businesses with a Glasgow postcode.
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 Glasgow businesses supplying NHS Scotland or Scottish Government, the scope needs to cover the systems that process or access public sector data - which typically includes cloud platforms and any externally accessible application. An external-only test of your corporate website will not satisfy a public sector contract requirement if your client-facing systems and data storage are out of scope. Define scope against your contract and compliance requirements.
Report quality: executive summary vs technical findings
For Glasgow businesses presenting audit results to a Scottish Government or NHS Scotland contract manager, report format matters. Public sector clients typically require a report that demonstrates findings have been identified, prioritised, and remediated - a raw technical output without a clear executive summary and risk-ranked findings list may not satisfy the contract requirement. Ask prospective firms whether their report format is accepted for Scottish Government or NHS Scotland supplier assurance, and review a redacted sample before selecting.
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. For Glasgow businesses with a public sector contract renewal date or an annual supplier assurance submission, the timeline between findings and remediation is often fixed. 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. For Glasgow businesses with public sector assurance requirements, a completed retest is often required to close the finding - a report showing vulnerabilities were identified but not formally retested may not satisfy the contract requirement. Whether the retest is included in the initial price or charged at full day rate makes a material difference to the total engagement cost. Pre-agree retest terms before the test starts.
Hidden costs and oversights that catch Glasgow 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 compliance requirement unmet.
Scope that excludes cloud assets and remote worker endpoints
Many standard pentest scopes cover on-premise servers and office systems but exclude cloud platforms (Microsoft 365, Azure, Google Workspace) and remote worker endpoints. For most Glasgow professional services and public sector suppliers, the majority of sensitive data and business-critical processes sit in cloud environments. A test that excludes these assets does not reflect where the real risk is, and may not satisfy a public sector contract requirement that specifies cloud environments must be in scope.
Firms that classify all findings as high severity to inflate remediation scope
Security audit reports that classify every finding as "Critical" or "High" regardless of actual exploitability are used to create urgency and drive remediation services. Glasgow businesses under public sector contract pressure are a common target - the combination of compliance deadlines and a procurement audience that is not always technically confident makes it easy to sell expensive remediation against inflated findings. Ask each firm how they calibrate severity and review a redacted previous report before selecting.
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 only confirms the fix worked by commissioning another engagement at full rate. For a five-day pentest at £6,000-£11,000, a retest of critical findings can add £2,500-£5,500 if not pre-agreed. For Glasgow firms with a fixed public sector submission date, an unplanned retest cost and the scheduling delay can push you past the deadline. 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 vulnerability 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 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 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 handled, and clear identification of any out-of-scope items.
Red flag: "We cover your infrastructure" without specifying cloud or remote assets.
Good answer: They provide a sample promptly, ideally from a public sector engagement. The sample shows clear severity ratings, an executive summary suitable for a non-technical contract manager, and confirms the format is accepted for public sector supplier assurance.
Red flag: "We can't share client reports due to confidentiality." A properly redacted sample has no confidential 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 for remediation support independent of findings.
Red flag: "We'll scope remediation once we've seen the findings." That is pricing at maximum leverage.
Good answer: A specific pre-agreed retest policy - one retest of critical and high findings within 90 days, included in the price, or a defined day rate agreed before the initial test.
Red flag: "We'll discuss retest pricing after the report is delivered."
Good answer: A clear explanation referencing CVSS, OWASP, or NCSC guidance with specific examples. The firm should acknowledge that not every engagement produces critical findings.
Red flag: A vague answer without methodology reference, or any implication 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
Glasgow businesses holding public sector contracts often need both Cyber Essentials Plus (for the contract itself) and a penetration test (for broader security assurance or a separate contract requirement). Commissioning both from the same firm removes the firm's cost of acquiring a second engagement and typically produces a 10-20% combined discount. Annual renewal commitments for Cyber Essentials can also attract a further discount.
Annual contract for quarterly vulnerability scanning plus an annual pentest
One-off penetration tests are priced as discrete engagements with no relationship value to the firm. An annual contract - quarterly automated vulnerability scanning plus one full pentest per year - fits naturally into the annual public sector contract renewal cycle that many Glasgow businesses already operate, and changes the firm's pricing calculus significantly.
Phase the test: external and cloud first, internal second
A phased approach - Phase 1 covering external infrastructure and cloud, Phase 2 covering internal systems - lets you assess the firm's work quality and report output before providing access to sensitive internal systems. Phase 1 findings also inform the Phase 2 scope, often producing a more focused internal test. Ask each firm to quote Phase 1 and Phase 2 separately.
Pre-agree the retest scope and price before the initial test
Once you have the findings report and a public sector submission deadline approaching, the security firm has significant leverage. Pre-agreeing retest scope and day rate before the initial test removes this entirely and allows you to commit to a verified completion timeline before testing begins.
Competitive quotes from two CREST-accredited firms
Glasgow has a smaller local market than major English cities, but running a structured RFQ process with two or three accredited firms - including Edinburgh-based and UK-wide firms that can deliver remotely - produces real competitive tension. Meaningful price variation exists for identical scopes even in a smaller market.
Timing: security firms have quieter periods in summer and over Christmas
Penetration testing firms have quieter periods in July to September and over the Christmas-New Year period. Testing at these times often produces better tester availability and sometimes a pricing concession. For Glasgow firms without a hard public sector submission deadline tied to a specific date, timing flexibility is worth building in.
