Cyber Security Consultancy UK
Precursor's consultancy is practical, delivery-led advice built on its accredited testing and SOC practice: ISO 27001 implementation, Cyber Essentials preparation, TLPT preparation, security architecture, and remediation guidance from testers who exploit real weaknesses, not a standalone advisory firm working from a template.
Most cyber security consultancy is written by people who have never run a live SOC shift or exploited a real vulnerability. Precursor's consultancy is delivered by the same CREST-accredited testers and SOC analysts who deliver our testing and monitoring services, turned toward ISO 27001, Cyber Essentials, TLPT preparation, and fixing what a test finds. Fixed-price, scoped after a call, no open-ended day rates.
What is cyber security consultancy?
Advice from the people who do the testing and run the SOC, not a firm that only advises.
Precursor's consultancy is practical, delivery-led advice built on its accredited testing and SOC practice: ISO 27001 implementation, Cyber Essentials preparation, TLPT preparation, security architecture, and remediation guidance from testers who exploit real weaknesses.
We do not run a standalone advisory practice detached from delivery. Read how our offensive and defensive teams share findings on our closed-loop security page.
What Our Consultancy
Covers
Four consultancy services, each delivered as a fixed-price, scoped engagement rather than an open day rate.
ISO 27001 Consultancy
Gap analysis, ISMS design, risk assessment, internal audit, and Stage 2 certification body liaison, delivered by consultants who hold ISO 27001 themselves. Fixed-price from £8,000.
Cyber Essentials Gap Analysis
Pre-assessment gap analysis against the five NCSC technical controls before your formal Cyber Essentials or Cyber Essentials Plus assessment, recommended for first-time applicants. From £500.
TLPT Preparation
DORA requires critical entities to run threat-led penetration testing every three years under the TIBER-EU framework. We prepare you for it: intelligence-led red team operations, threat-scenario scoping, detection and response validation, and remediation, so you enter the formal engagement ready. We prepare you for TLPT; the formal test itself is run by framework-registered providers.
Remediation Consultancy
Once a penetration test lands, we help you fix what it found: prioritised remediation guidance, direct engineer access via our reporting portal, and a 30-day retest window included on every engagement to verify the fix actually worked.
Advice from the people doing the work.
Our consultants are not a separate advisory arm. The same firm that tests your systems and monitors your alerts also writes your ISMS and prioritises your remediation.
Consultants who also test
Precursor is CREST accredited across penetration testing from £2,500, vulnerability assessment, and SOC operations. When we advise on an ISMS control or a DORA gap, we are describing the same weaknesses our testers exploit on live engagements, not a control described only in a textbook.
Shaped by live SOC data
Our managed SOC in Newcastle, from £900/month, runs from a physical UK facility with DBS-checked analysts and critical alerts investigated within 10 minutes. That operational reality informs how we prioritise every remediation and compliance recommendation. See how it connects to testing on our closed-loop security page.
Accreditation you can check, not take on trust.
Every accreditation we claim is verifiable in a public register. Check before you buy: it is the same advice we would give you about any provider, including us.
- 01
Triple CREST accreditation.
Precursor holds CREST company accreditation for penetration testing, vulnerability assessment, and SOC operations, checkable directly in the CREST member directory before you ever speak to us.
- 02
Certified in our own operations.
We hold ISO 27001 and Cyber Essentials Plus for our own operations: the frameworks we advise on are the frameworks we run internally, audited the same way yours will be.
- 03
Advice from practitioners.
The consultants advising you are the same CREST-accredited testers and SOC analysts who deliver our engagements: UK-based, DBS-checked employees, not a bench of career advisers working from a template.
Fixed-price, scoped engagements.
Every consultancy engagement is quoted as a fixed price after a scoping call, not billed against an open-ended day rate. Two services carry a published starting price; the rest are scoped to your environment.
No open-ended day rates. TLPT preparation and remediation consultancy are scoped to your environment on a scoping call, then quoted as a fixed price, the same commitment we make on ISO 27001 and Cyber Essentials.
Get a Scoping CallSituations We See Regularly
Most consultancy engagements are triggered by one of these four scenarios. If any apply, you are in the right place.
You have a compliance deadline
A client, insurer, or procurement team has specified ISO 27001 or Cyber Essentials, often with a date already running. We start with a gap analysis scoped against the actual standard.
You have EU financial exposure
UK firms with EU subsidiaries, EU clients, or ICT relationships with EU financial entities fall within DORA's scope. We assess readiness across all five pillars before your regulator does.
You have findings to fix
A penetration test or audit has already told you what is wrong. Remediation consultancy prioritises the fixes, gives your engineers direct access to the testers who found the issue, and verifies the fix in the included retest window.
You want advice from practitioners
You want a second opinion or a security roadmap from people who actually run CREST-accredited tests and monitor a live SOC, not a standalone advisory firm working from a compliance template.

Compliance deadline, DORA exposure, findings to fix, or a security roadmap. Tell us where you are starting from and we will send back a fixed-price quote for the right consultancy engagement.
Cyber Security Consultancy: common questions.
What we cover, how we price it, and how to check who you are hiring.
A cyber security consultancy advises an organisation on its security posture and helps close the gaps that advice identifies: compliance frameworks such as ISO 27001, Cyber Essentials, and DORA, security architecture review, and remediation guidance after a test or audit finds weaknesses. Precursor's consultancy work is delivered by the same CREST-accredited testers and SOC analysts who run our penetration testing and managed SOC services, so the advice is grounded in what we actually see exploited and monitored, not written by a standalone advisory team working from a template.
There is no single price because scope varies by engagement type. Two of our consultancy services carry a published starting price:
- ISO 27001 consultancy: from £8,000 (typically £8,000-£25,000 depending on organisation size and scope).
- Cyber Essentials pre-assessment gap analysis: from £500.
TLPT preparation, security architecture review, and remediation consultancy following a penetration test are scoped individually and quoted as a fixed price after a call. We do not sell consultancy on an open-ended day rate.
Consultancy is project-based advice with a defined start and end: a gap analysis, an ISMS build, TLPT preparation, or remediation guidance after a test. Managed services, our SOC and MDR, are ongoing operational delivery: 24/7 monitoring, alert triage, and incident response. Many clients use both: consultancy to design the framework and pass certification, then managed services to keep the evidence current between audits. See our managed SOC service for the operational side.
It depends on where you are starting from. If you already know your compliance target, ISO 27001, Cyber Essentials, or DORA, start with a gap analysis so the consultancy work is scoped against the actual standard. If you do not have a specific compliance deadline and want to know where your real weaknesses are, a penetration test comes first: it gives you evidence of exploitable issues, and remediation consultancy then helps you fix them in priority order rather than patch everything at once.
Look for a consultancy that holds CREST company accreditation for the testing work behind its advice, and check any accreditation claim directly in CREST's public member directory rather than taking a badge on trust. Precursor Security holds CREST accreditation for penetration testing, vulnerability assessment, and SOC operations, alongside ISO 27001 and Cyber Essentials Plus certification for our own operations. Verify any provider's claims in the public registers rather than taking a badge on trust; ours are checkable at crest-approved.org.
