Website Security for Enterprise Clients
Website security for enterprise clients across Europe: managed monitoring, testing and 24/7 response mapped to ISO 27001, DORA and NIS2. Get a scoped quote.
Website security for enterprise clients is not a bigger version of small-business protection; it is a different problem. You have many applications, several environments, compliance obligations with real penalties, and an attack surface that changes every time a team ships. We run a managed enterprise security programme that watches all of it, tests it on a schedule, and responds around the clock, mapped to the frameworks your board answers to.
At enterprise scale the risk is rarely a single unpatched plugin. It is the forgotten subdomain from a marketing campaign, the acquired company’s stack that never got integrated, the internal admin tool exposed to the internet by mistake, the third-party integration nobody security-reviewed. Attackers look for the weakest point across the whole estate, so protection has to cover the whole estate, continuously, not one flagship site once a year.
What enterprise web security covers
An enterprise programme combines continuous defence with regular offensive testing and a response capability that is ready before you need it. The point is coverage that scales with your organisation and gives your CISO evidence, not just reassurance. Here is the shape of what we run.
Beyond the flagship site
The mistake most enterprise security makes is over-focusing on the main revenue application while the edges rot. Attackers do the opposite; they map your whole external footprint and go for the weakest link. Our programme starts with attack-surface discovery so you have an accurate, living inventory of what is actually exposed, then keeps watching it as teams spin up new services. Enterprise cyber security only works when it covers the assets nobody remembered.
A programme, not a product
Enterprise cyber security tools matter, but tools without an operating model produce noise. We run the programme: define what “normal” looks like across your environments, tune detection so the alerts that reach your team are real, schedule the offensive testing, and keep the whole thing aligned to your risk appetite and compliance calendar. The enterprise cyber security strategy is the deliverable, and the tooling serves it rather than the other way round.
How the programme runs
An enterprise engagement is structured around your governance, not ours. We integrate with your change process, your ticketing, and your reporting cadence so security becomes part of how the organisation already works.
Discovery and baseline
We build a complete inventory of your internet-facing assets: domains, subdomains, applications, APIs, cloud services and the third-party integrations hanging off them. Each is assessed against a secure baseline. This first phase almost always finds exposed assets the organisation did not know were live, which is exactly why it comes first.
Continuous monitoring and testing
From the baseline, monitoring runs continuously while offensive testing runs on a schedule keyed to risk: critical applications tested more often, lower-risk ones on a longer cycle. New releases and major changes trigger a targeted assessment rather than waiting for the next annual test, so the window between “shipped” and “tested” stays short.
Response and reporting
When something happens, our 24/7 team responds under the SLA you agreed, contains it, and works the incident to a clean resolution. Between incidents, reporting gives your CISO and board what they need: risk trends, test results, remediation status, and evidence mapped to your compliance obligations. This is the material that turns a security programme into something the board can actually govern.
The enterprise threats we plan for
Scale changes the threat model. A few risks matter far more at enterprise size than they do for a single site.
Shadow IT and forgotten assets
Marketing microsites, old campaign domains, proof-of-concept apps left running, subdomains pointing at decommissioned services. Each is a potential entry point, and subdomain takeover is a real and common finding. Continuous discovery keeps this under control instead of letting it accumulate.
Supply chain and third-party risk
Your applications pull in scripts, SDKs and services from other companies. A compromise in one of them becomes a compromise in you, as several large European breaches have shown. We map these dependencies and test how much trust each one is really given.
Application-layer attacks at scale
Injection, broken access control, business-logic flaws and authentication weaknesses do not disappear because you are large; they multiply across more applications. Manual testing across the estate finds the IDOR, SSRF and privilege-escalation issues that scanners miss and that lead to the biggest breaches.
Insider and lateral movement risk
Enterprise environments are interconnected, so a foothold in one place can become access to many. Our testing looks at what an attacker who gets one step in can reach next, which is often the difference between a contained incident and a headline.

Why manual testing is non-negotiable at this level
Automated scanning has a role in an enterprise programme for breadth and speed, and we use it. But the findings that end up in serious breach reports are almost never things a scanner flags. They are broken authorization between two user roles, a business-logic flaw in a checkout or transfer flow, a chain of small issues that individually look minor. Finding those requires an engineer who understands the application and thinks like an attacker. Our offensive team holds OSCP and OSWE certifications and tests by hand with Burp Suite and manual analysis, then verifies every finding so what reaches your team is real and reproducible, not a probability score.
Evidence your auditors and board trust
Each finding comes with impact, a CVSS score, exact reproduction steps and a prioritised fix. That evidence maps onto OWASP ASVS, the MITRE ATT&CK techniques it relates to, and the specific control in whichever framework you report against. When an auditor or a board member asks “how do we know this is real,” you have the answer on paper.
How we fit into your organisation
An external security programme only works if it plugs into how your teams already operate. We are deliberately not a black box that emails a PDF once a quarter.
Integrated with your workflow
Findings can flow into your ticketing system so remediation lands with the right team and is tracked to closure. We join your security stand-ups or governance meetings at whatever cadence suits, and the dedicated engineer becomes a known contact your developers can reach rather than a stranger who reappears at audit time.
Aligned to your risk appetite
Not every finding is an emergency, and treating them all as one burns out your teams. We prioritise against your actual risk profile and business context, so effort goes where it reduces the most exposure. That triage, done by someone who understands both the technical severity and what the asset is worth to you, is a large part of the value.
Knowledge that stays with you
Where useful, we run short briefings for your developers on the classes of issue we keep finding in your code, so the same mistakes stop recurring. Security that only ever finds problems and never teaches is a treadmill; we would rather your applications get genuinely harder to break over time.
Compliance across European frameworks
Enterprise security in Europe now sits under a stack of overlapping obligations, and the newer ones carry serious enforcement.
DORA and NIS2
If you are a financial entity, DORA sets expectations for operational resilience testing, including threat-led testing of critical systems. NIS2 extends security and incident-reporting duties across a much wider set of sectors than its predecessor. Our programme is built to produce the testing evidence and incident records both regimes expect, aligned to the specific obligations that apply to your organisation.
ISO 27001, SOC 2 and PCI DSS
For your certification programme, we map testing and monitoring to ISO 27001 Annex A controls, provide the external-testing evidence SOC 2 auditors ask for, and satisfy PCI DSS requirement 11 for penetration testing where card data is in scope. One programme, evidence for all of them.
Confidentiality and data handling
We work under a mutual NDA with data-handling terms that fit enterprise procurement. Findings, credentials and any data are held on encrypted storage, access is limited to the assigned team, and retention follows your policy.
