Penetration testing from our Edinburgh office at 83 Princes Street: web applications, infrastructure, cloud, and mobile, delivered for Scotland's fintech, banking, and public sector organisations with local, in-person engagement.
Local testing for Scotland's
financial capital.
Edinburgh holds the UK's second-largest financial services concentration, a globally ranked fintech cluster, and the Scottish Government's digital estate. The testing demands are correspondingly formal: regulated firms need accredited providers with audit-ready reporting, fintechs need testing that satisfies banking partners and enterprise customers, and public bodies need Scottish-based delivery with clear data handling. Our Princes Street office puts CREST-accredited testers on the ground in the city, with the full UK team behind them.
Who We Test In Edinburgh
Testing scoped to the sectors that define Edinburgh's economy, because a meaningful penetration test starts from who actually attacks businesses like yours, and what they are after.
How We Reach You
Edinburgh is served from our Edinburgh office. Our office at 83 Princes Street is in the heart of the city, minutes from Waverley 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.
Edinburgh 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. In-person scoping and debriefs at our Princes Street office, with on-site testing across Edinburgh, the Lothians, and Fife.
Every Test,
Delivered In Edinburgh.
The full offensive security portfolio is available to Edinburgh 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 Edinburgh
Manual, CREST-accredited testing of the web applications and APIs your Edinburgh 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 Edinburgh
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 Edinburgh.
Cloud Penetration Testing Edinburgh
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 Edinburgh
On-site assessment of your wireless estate in Edinburgh: rogue access point detection, segregation between guest and corporate networks, and attacks against enterprise authentication.
Mobile Application Testing Edinburgh
iOS and Android application assessments covering insecure storage, API trust boundaries, and platform hardening, for Edinburgh businesses shipping mobile products or internal apps.
Cyber Essentials & Compliance Edinburgh
Cyber Essentials and Cyber Essentials Plus certification, ISO 27001 support, and PCI DSS testing for Edinburgh organisations that need recognised certification alongside technical assurance.
Threat Detection & Response for Edinburgh, 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 Edinburgh organisations, delivered entirely from UK soil.
Explore Defensive SecurityHow Engagements Run In Edinburgh.
From first call to free retest. Every Edinburgh 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. Edinburgh clients can scope by video call or, where practical, in person via our Edinburgh office.
Testing In Edinburgh
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 Edinburgh. 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 Edinburgh or at our Edinburgh office 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.
