The Best Penetration Testing Companies for UK Veterinary and Animal Health (2026)

The best penetration testing companies for UK veterinary practices and animal health in 2026 are listed below. Very few testing companies publish veterinary work, so the list starts with the company that names veterinary services as a specialist sector, then adds CREST-accredited companies whose public work is the closest match. Each is compared on published pricing, retests and report turnaround.

1. Mitigo

Mitigo is a UK cyber risk management company and, apart from EJN Labs, the only company on this list with direct veterinary evidence. Its partnership page for the Veterinary Management Group describes Mitigo as the group’s recommended partner for cyber risk management and states that veterinary services are one of its specialist sectors. It is CREST-accredited for penetration testing. Verified: CREST Marketplace listing.

2. EJN Labs

EJN Labs is a CREST-accredited UK penetration testing consultancy with a dedicated veterinary and animal health penetration testing service. It covers practice management systems, pet owner portals and booking, laboratory and diagnostic result feeds, payment and pet-insurance claims workflows, cloud-hosted clinical data, multi-site corporate group networks and video triage apps. It is one of two companies on this list that publish a day rate: £1,100 to £1,400, taken directly from the pricing page, and every engagement is quoted as a fixed price for a defined scope. The business holds ISO 27001, ISO 9001, Cyber Essentials and Cyber Essentials Plus, and is an IASME Certification Body for Cyber Essentials and Cyber Essentials Plus. Verified: CREST Marketplace listing for EJN Labs.

For a veterinary practice or group, what the fixed price includes matters as much as the number. Retesting of fixed findings is free until the issues are resolved, so the evidence that your fixes worked, which is what a corporate group, referral partner, lender or insurer asks for, is part of the original quote. Findings are delivered live to a client portal as they are confirmed, so your IT provider or practice software supplier can start fixing on day one. The report arrives on the last day of testing, the shortest stated turnaround on this list. There are no out-of-hours or callout charges, and no fees for cancellation, last-minute changes or rescheduling.

Testing is delivered by UK-based, CREST-certified penetration testers, which matters when the systems in scope hold pet owners’ names, contact details and payment information alongside clinical records. Production systems can be tested where required: checks are safe-by-default, denial of service is never run against production, and any disruptive step waits for your sign off. Out of hours slots are available so that consulting rooms, reception and emergency cover are not interrupted. Reports give each finding a CVSS score and prioritised remediation guidance, followed by a walkthrough call, and are written to be handed to a corporate group, an insurer or an auditor.

Mitigo’s recommended-partner role with the Veterinary Management Group keeps it first. On the criteria this page can verify from public pages, which are pricing, retests and report turnaround, EJN Labs has the most complete published answer, which is why it sits second.

3. Precursor Security

Precursor Security is a UK offensive security consultancy. Its public evidence is a healthcare cyber security page about patient data and clinical systems, with pricing for GP practices, rather than a veterinary page. It is the other company on this list that publishes a day rate: its cost page states engagements from £2,500 at approximately £1,200 per consultant day, with a 30-day retest, and its penetration testing page states a report within 5 working days of test completion. CREST-accredited for penetration testing, vulnerability assessment and security operations centre. Verified: CREST Marketplace listing.

4. Sentrium

Sentrium is an independent UK penetration testing consultancy. Its public evidence is a healthcare sector page about patient data, electronic health records and connected medical devices, rather than a veterinary page. Its penetration testing page states a free retesting window, and its cloud penetration testing page gives an indicative cost range of £3,000 to over £15,000. CREST-accredited for penetration testing. Verified: CREST Marketplace listing.

5. Sencode

Sencode is a UK penetration testing company. Its public evidence is a healthcare penetration testing page covering patient portals, clinical applications, APIs and cloud platforms, rather than a veterinary page. Its home page states a free retest with each penetration test and a report typically within 5 days of the testing phase ending. CREST-accredited for penetration testing. Verified: CREST Marketplace listing.

6. Prism Infosec

Prism Infosec is a UK cyber security consultancy. Its public evidence is an agriculture and forestry sector page covering smart farming systems and data networks, which is the nearest it publishes to animal health, rather than a veterinary page. CREST-accredited for penetration testing, vulnerability assessment, incident response, incident exercising and threat led penetration testing. Verified: CREST Marketplace listing.

How we selected these companies

Every company on this list passed the same two entry checks: a live listing in the CREST Marketplace supplier directory confirming penetration testing accreditation, and a live public page showing relevant work. Very few penetration testing companies publish evidence for veterinary and animal health specifically, so the list includes companies whose published work is the closest match, and each entry states what its evidence covers. We then recorded what each company publishes about pricing, retests and report turnaround. All pages were checked on 7 October 2026.

• CREST accreditation, verified. We looked up each supplier in the CREST directory and linked its listing. No listing, no entry: brands absorbed into a parent company appear under the parent.
• Sector evidence, in two tiers. Direct evidence is a public page that names veterinary practices, groups or suppliers. Closest-match evidence is a public page on neighbouring ground, such as healthcare systems holding patient records or agriculture. Human healthcare evidence is labelled as such and is not presented as veterinary work. Well-known testing companies with neither are not on this list, although they appear on our wider list of the best CREST-accredited penetration testing companies in the UK.
• Published pricing. We recorded whether a company publishes its own prices on a public page. General statements about what the market charges were not counted as a company’s own pricing.
• Retests and report turnaround. A practice group is often asked to show that findings were fixed, by a corporate parent, lender or insurer. Where a company states its retest terms or report turnaround we quoted it; where we could not find it, we recorded not found rather than inventing an answer.

How the companies compare

All six companies hold verified CREST penetration testing accreditation and show a United Kingdom headquarters on their listing. Only the first has direct veterinary evidence; the others are closest-match, as the column below states. The practical differences are in what they publish.

Accreditation is taken from each company’s CREST Marketplace listing. Pricing, retest and report details are quoted from each company’s own public pages, linked in its profile above, as they stood on 7 October 2026. Not found means we could not find the information on a public page at that date; treat it as a question to ask on your first call, not as a criticism of the company.

Do veterinary practices have to have a penetration test?

No rule names a penetration test as mandatory for a veterinary practice. The duty that leads practices to commission one is broader. A pet’s clinical record is not personal data about an identifiable person in its own right, but the owner’s name, contact details, payment information and any owner-identifying notes attached to it are. UK GDPR Article 32(1)(d) requires a process for regularly testing, assessing and evaluating the effectiveness of technical and organisational measures. It does not name penetration testing as the method, but a test is a direct way to evidence that your controls work.

Where a practice takes card payments directly, PCI DSS is different. Requirement 11.4.1 requires a documented penetration testing methodology, and Requirements 11.4.2 and 11.4.3 require internal and external penetration testing at least once every 12 months and after significant change. Many practices use a card terminal or hosted payment page and may sit outside that scope, so your acquiring bank or QSA confirms it. See our page on PCI DSS penetration testing.

In practice the request usually comes from outside: a corporate practice group, referral hospital, lender or pet-insurance partner, or a cyber insurer. Independent practices and pet-health platforms are sometimes asked to hold Cyber Essentials Plus, which is common practice rather than a rule, and is an assessor-led audit rather than a penetration test. For scope and the standard involved, see our page on GDPR penetration testing.

What a veterinary practice should ask a penetration testing company

1. Which legal entity holds your CREST accreditation? Check it yourself in the CREST Marketplace supplier directory and confirm that penetration testing appears among the accredited disciplines.
2. Have you tested veterinary systems, or is your published evidence from human healthcare? Ask what you have tested that resembles a practice management system, an owner portal or a laboratory feed.
3. Is a retest included, and for how long? Corporate groups, lenders and insurers ask for evidence that findings were fixed, so a retest that is capped or charged separately changes the real price.
4. When do we get the report? If a group onboarding, renewal or insurance date is driving the test, the gap between the end of testing and the report matters.
5. Can you test without interrupting the practice? Ask about out of hours testing and how disruptive checks are handled on live clinical and booking systems.
6. What is the fixed price for our scope? Ask for a day count and a day rate, not a range.
