Penetration Testing Leeds
Precursor Security delivers CREST-accredited penetration testing in Leeds from our city centre headquarters, where our full team of CREST Registered Testers is based. Because Leeds is our home city, on-site web application, infrastructure, and wireless testing can be scheduled faster here than anywhere else in the UK, often within days, with in-person scoping and debrief meetings at our HQ.
Penetration testing from the company headquartered in Leeds city centre. Our full CREST-certified testing team is based here, which means same-week on-site testing, in-person scoping meetings, and face-to-face debriefs for West Yorkshire organisations.
The pen test team that is already
in Leeds.
Leeds is the UK's largest financial and legal services centre outside London, hosts a major NHS digital footprint, and anchors a healthtech and data science cluster that keeps growing. Those sectors share one property: they are regulated, and their testing requirements come with audit trails, data residency demands, and short remediation windows. Being headquartered in the city means our testers can be in your office the same week, your data never leaves the UK, and your debrief happens across a table rather than a video call.
Who We Test In Leeds
Testing scoped to the sectors that define Leeds's economy, because a meaningful penetration test starts from who actually attacks businesses like yours, and what they are after.
How We Reach You
Leeds is served from our Leeds headquarters. Our headquarters is in Leeds city centre, ten minutes from the railway station.
CREST-Accredited, Verifiably
Precursor Security holds CREST organisational accreditation for penetration testing, independently audited across methodology, QA, and tester competency. Every engagement letter carries our membership number for direct verification by your auditors, insurers, or customers.
No Travel Games. No Scanner Reports. No Offshoring.
Leeds clients get the same team, methodology, and day rate as our London and Leeds clients: manual testing by employed, UK-based CREST Registered Testers, fixed quotes agreed at scoping, immediate escalation of critical findings, and free retesting of everything you fix. Same-week on-site testing anywhere in Leeds and West Yorkshire, plus in-person scoping and debrief meetings at our city centre HQ.
Every Test,
Delivered In Leeds.
The full offensive security portfolio is available to Leeds organisations. Each service links to its full methodology, and every engagement ends with reporting your engineers can action and your auditors can file.
Web Application Penetration Testing Leeds
Manual, CREST-accredited testing of the web applications and APIs your Leeds business depends on. Full OWASP coverage plus the business logic and access control flaws automated scanners miss, with free retesting of every finding.
Internal & External Network Testing Leeds
External testing of your internet-facing perimeter, and internal testing that maps what an attacker could reach once inside: Active Directory attack paths, lateral movement, and privilege escalation. On-site delivery in Leeds.
Cloud Penetration Testing Leeds
Configuration review and attack-path testing across AWS, Azure, Microsoft 365, and GCP. We find the identity misconfigurations, exposed storage, and over-privileged roles that cause most real cloud breaches.
Wireless Network Testing Leeds
On-site assessment of your wireless estate in Leeds: rogue access point detection, segregation between guest and corporate networks, and attacks against enterprise authentication.
Mobile Application Testing Leeds
iOS and Android application assessments covering insecure storage, API trust boundaries, and platform hardening, for Leeds businesses shipping mobile products or internal apps.
Cyber Essentials & Compliance Leeds
Cyber Essentials and Cyber Essentials Plus certification, ISO 27001 support, and PCI DSS testing for Leeds organisations that need recognised certification alongside technical assurance.
Threat Detection & Response for Leeds, 24/7.
A penetration test proves what an attacker could do today. Our UK Security Operations Centre watches for the ones who try tomorrow: managed detection and response, a CREST-accredited SOC, and incident response for Leeds organisations, delivered entirely from UK soil.
Explore Defensive SecurityHow Engagements Run In Leeds.
From first call to free retest. Every Leeds engagement is managed by a named account manager with direct access to the testing team, no ticket queues between you and the people doing the work.
Scoping & Fixed Quote
A free scoping call, usually within 24 hours of your enquiry, where a technical consultant (not a salesperson) defines what needs testing, agrees the approach, and produces a fixed quote. Leeds clients can scope by video call or, where practical, in person via our Leeds headquarters.
Testing In Leeds
CREST Registered Testers execute the engagement during agreed windows: remote phases for external, web, and cloud testing, and on-site or appliance-based delivery for internal and wireless work in Leeds. You get daily progress updates, and critical findings are escalated immediately rather than saved for the report.
Reporting Built for Two Audiences
Every report contains an executive summary your board and customers can read, and a technical annex your engineers can action: reproduction steps, evidence, CVSS scoring, and specific remediation guidance. Reports are quality-assured before delivery and structured for auditors, insurers, and customer due diligence reviews.
Debrief & Free Retesting
A full debrief walks your team through findings and attack chains, in person in Leeds or at our Leeds headquarters where practical, or by video call. Once you have remediated, we retest the fixed findings free of charge and issue updated reporting, so your evidence shows issues closed, not just found.
The best time to test your defences is now.
