Penetration Testing Cheshire
Precursor Security provides CREST-accredited penetration testing across Cheshire, including Chester, Warrington, Crewe, Macclesfield, and the surrounding county. We test web applications, internal and external infrastructure, wireless, and cloud environments, with on-site delivery county-wide from our Leeds headquarters, around 90 minutes away.
CREST-accredited penetration testing for Cheshire businesses: web applications, infrastructure, wireless, and cloud. On-site coverage for Chester, Warrington, Crewe, and Macclesfield, delivered from our Leeds headquarters.
Testing for Cheshire's quietly
critical industries.
Cheshire hosts more critical industry than most counties: pharmaceutical and chemical manufacturing around the Mersey belt, financial services operations in Chester, nuclear and energy engineering, rail engineering at Crewe, and a science corridor at Alderley Park and Daresbury. These are environments where security failures have regulatory and physical consequences, and where supply chain assurance requirements arrive from pharmaceutical, energy, and financial primes. We deliver accredited testing calibrated to that profile, including OT-aware assessment for manufacturing and process environments.
Who We Test Across Cheshire
Testing scoped to the sectors that define Cheshire's economy, because a meaningful penetration test starts from who actually attacks businesses like yours, and what they are after.
How We Reach You
Cheshire is served from our Leeds headquarters. Around 90 minutes from most of Cheshire via the M62 and M6.
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.
Cheshire 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. On-site internal, wireless, and OT-adjacent testing across Chester, Warrington, Crewe, Macclesfield, and the wider county.
Every Test,
Delivered Across Cheshire.
The full offensive security portfolio is available to Cheshire 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 Cheshire
Manual, CREST-accredited testing of the web applications and APIs your Cheshire 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 Cheshire
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 across Cheshire.
Cloud Penetration Testing Cheshire
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 Cheshire
On-site assessment of your wireless estate across Cheshire: rogue access point detection, segregation between guest and corporate networks, and attacks against enterprise authentication.
Mobile Application Testing Cheshire
iOS and Android application assessments covering insecure storage, API trust boundaries, and platform hardening, for Cheshire businesses shipping mobile products or internal apps.
Cyber Essentials & Compliance Cheshire
Cyber Essentials and Cyber Essentials Plus certification, ISO 27001 support, and PCI DSS testing for Cheshire organisations that need recognised certification alongside technical assurance.
Threat Detection & Response Across Cheshire, 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 Cheshire organisations, delivered entirely from UK soil.
Explore Defensive SecurityHow Engagements Run Across Cheshire.
From first call to free retest. Every Cheshire 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. Cheshire clients can scope by video call or, where practical, in person via our Leeds headquarters.
Testing Across Cheshire
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 across Cheshire. 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 across Cheshire 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.
