Penetration Testing in Glasgow
Penetration testing for organisations in Glasgow and across the west of Scotland, delivered on site by Cyber Scheme and CREST qualified testers. Fixed-price proposals within 24 hours. Every engagement includes a free retest.
Overview
JAG Secure is a senior-led penetration testing consultancy headquartered in Edinburgh. Glasgow is under an hour away, which means in-person scoping meetings, on-site internal testing and a face-to-face debrief are all standard rather than something you pay extra for. Testing is delivered by consultants holding Cyber Scheme and CREST qualifications, led by a Principal-registered (PriCSP) tester. We test web applications, APIs, external and internal infrastructure, cloud environments, mobile applications and wireless networks.
Working in Glasgow
We are regularly in the city centre, the financial district around Bothwell Street, the university quarter and the business parks along the M8 and M74 corridors. Paisley, East Kilbride, Motherwell, Hamilton and Cumbernauld are the same trip. Internal testing is done on your premises with our own equipment, arranged around your change windows. If you would rather not have a consultant on site, a pre-configured testing device can be shipped to plug into your network instead. External, web application and API testing is delivered remotely.
Why a Scottish Consultancy
Most penetration testing sold into Glasgow is delivered from England by people you will never meet. We are based in Scotland. The person who scopes your test is the person who turns up to do it and the person who presents the findings to your board. JAG Secure is a member of ScotlandIS and the Edinburgh Chamber of Commerce and was named a finalist for Cyber Start-up of the Year at the Scottish Cyber Awards 2026.
Penetration Testing for Glasgow Organisations
Financial Services
Glasgow hosts the operations and technology centres of several banks, insurers and investment managers, along with the fintechs that supply them. These teams are asked for independent testing by regulators, auditors and their own head offices. We test customer-facing web applications and APIs, the internal networks and Active Directory that sit behind them. We also review the cloud tenancies they are migrating to. Reports are written to satisfy an internal audit function as well as the engineers who fix the findings.
Universities and Colleges
Glasgow has three universities and a large college sector, each running research networks, student systems and remote access for tens of thousands of users. We have delivered external, internal Active Directory and remote-access VPN testing for Scottish higher education. Engagements are scoped around term dates and reports are written to satisfy Jisc, funder and audit questions as well as the IT team.
Healthcare and Health Technology
NHS boards, their suppliers and the health technology companies clustered around the city hold some of the most sensitive data in the country. We have tested patient-facing web and mobile applications and the APIs behind them for health technology providers. Testing is scoped to respect clinical safety, patient data handling and the assurance frameworks suppliers must evidence to sell into the NHS.
Law Firms and Professional Services
Glasgow’s law firms, accountants and consultancies hold client funds, privileged correspondence and identity documents. Insurers and corporate clients increasingly ask them to evidence independent testing. We test case management platforms, client portals, Microsoft 365 tenancies and the internal networks that connect them. The report is written in language a managing partner can put in front of an insurer or a regulator.
How an Engagement Works
Every engagement is scoped and delivered by a senior qualified consultant, not handed to a junior after the contract is signed. You receive a fixed-price proposal within 24 hours of scoping. Testing is mapped to standards such as ISO 27001, Cyber Essentials Plus and PCI DSS. The report is written for both technical teams and leadership. Once you have remediated, we verify your fixes at no extra cost.
