Good website security services keep attackers out of your site, catch the ones who try, and give you evidence you can hand to an auditor or a board. SafetyBis works with businesses across Europe to lock down public-facing web applications, from a single WordPress brochure site to a multi-tenant SaaS platform, using manual testing rather than a scanner report you have to interpret yourself.
Most breaches we clean up did not need a genius attacker. They needed an unpatched plugin, a form that trusted user input, or an admin login exposed to the whole internet with no rate limiting. Web security is mostly about closing those gaps before someone else finds them, then watching for the ones that reopen.
What website security services actually cover
The phrase gets used loosely, so here is what it means when we say it. We are talking about the full lifecycle of protecting a live site: finding the holes, fixing them, keeping watch, and being ready when something goes wrong. That is broader than a one-time scan and narrower than “we do everything,” which usually means nobody owns the outcome.
Some clients want all of it under one managed plan. Others already have a developer and just need us to test and advise. Both are fine. What we will not do is sell you a dashboard and call it protection.
Web security services versus a plugin
Security plugins and firewalls have their place, and we install and tune them. But a plugin follows rules written for the average site. It does not understand that your checkout lets a logged-in user change the price field, or that your password reset link never expires. Human testing catches the logic flaws that automated tools score as “informational” and skip.
Where WSS and API security fit
If your platform exposes SOAP or web services, the security model is different from a normal login form. We check how the WS-Security UsernameToken profile is applied, whether tokens are actually validated server-side, and whether the service leaks internal detail through verbose faults. The same care applies to REST and GraphQL endpoints, which are now the most common way sensitive data walks out of a site.
How we deliver website security services
Every engagement starts with the same question: what would actually hurt you if it were compromised? A marketing site and a payment platform have very different worst days, and the work should reflect that. We scope around your real risk, not a generic checklist.
Assessment
We map the attack surface: every input, every login, every third-party integration, the CMS and its plugins, the hosting, and anything exposed that should not be. Tools like Burp Suite, nmap and ffuf do the heavy enumeration, then an engineer works through the interesting parts by hand.
Hardening and fixes
Findings come with the fix, not just the problem. That might mean patching a vulnerable component, rewriting an access-control check, tightening a content security policy, or moving an admin panel behind authentication and IP restriction. Where you host on AWS, we bring the relevant Amazon Web Services security best practices into the review: locked-down S3 buckets, least-privilege IAM, and no security groups open to the world.
Monitoring and response
Once a site is clean, the job is keeping it that way. Continuous monitoring watches for file integrity changes, unexpected admin accounts, outbound traffic to known-bad hosts, and search-engine blacklisting. If something trips, our 24/7 incident response team can be on it the same hour rather than the following Monday.
What monitoring actually watches
File hashes on the web root, the list of admin and privileged users, plugin and core versions against known vulnerability feeds, TLS certificate expiry, and DNS records. A quiet week is the point, not a failure of the service.
Common website security issues we find
The same handful of problems account for most of what we report. None of them are exotic. All of them are exploitable.
Injection and cross-site scripting
SQL injection is less common than it was, but it still shows up in older custom code and in search or reporting features nobody thought of as sensitive. Stored XSS is more frequent: a comment, a profile field or a support ticket that renders attacker-controlled markup back to an admin, quietly stealing a session.
Broken access control
This is the number one category in the OWASP Top 10 for a reason. IDOR flaws let a user change an ID in a URL and read someone else’s invoice. Missing server-side checks let a normal account hit admin-only actions. We test these by trying, not by reading documentation.
Outdated components and weak configuration
An out-of-date plugin or library is the entry point in the majority of the WordPress and CMS compromises we handle. Alongside that sit the boring but dangerous misconfigurations: directory listing left on, backups sitting in the web root, debug mode enabled in production, error pages that print stack traces and database paths.

Managed protection versus one-off work
You can buy website protection services as a project or as an ongoing plan, and the right answer depends on how your site changes. A static site that rarely gets touched may only need a hardening pass and a firewall. A site with an active dev team shipping weekly needs eyes on it continuously, because every release is a chance to reintroduce a hole.
When a project is enough
If you are launching, migrating, or responding to a specific worry, a fixed-scope engagement gives you a clear before-and-after. You get the report, the fixes go in, we retest, and you are done until the next big change.
When you want a plan
Compliance obligations, customer data, or a history of getting hit all point toward a monthly plan. It spreads the cost, keeps monitoring live, and means the people who know your site are already briefed when something happens at 2am.
Compliance and standards
Security work that cannot be shown to an auditor is only half done for a regulated business. We write reports to be handed straight into your compliance process.
Which frameworks we map to
PCI DSS 4.0, which requires regular testing under requirement 11.4 if you touch card data. ISO 27001 Annex A controls, including A.12.6 on technical vulnerability management. SOC 2 for the security trust criteria. And GDPR, where a demonstrable security process is part of showing you protect personal data. For firms in scope of NIS2 or DORA, we align the deliverables to those obligations too.
The attestation letter
On request, you get a signed letter stating what was tested, when, by whom, and that identified issues were retested after remediation. That is usually what a customer’s procurement team or your own auditor actually asks for.
What you get
No engagement ends with a raw tool export. You receive an executive summary written for non-technical stakeholders and a technical report your developers can work straight from.
Why manual testing beats an automated scanner
Automated scanners are fast and cheap, and they are the right tool for catching known, patchable issues at scale. They are also where a lot of “security services” quietly stop. The problem is that a scanner reports what it recognises, floods you with low-value noise, and stays silent on the things that actually get sites breached.
What a scanner cannot see
A scanner does not know that your API returns another customer’s order when you increment an ID, because to the tool that is just a valid response. It cannot reason that a two-step checkout can be skipped to the confirmation page, or that a support agent role can quietly reach billing functions. Business logic has no signature, so only a person testing the way an attacker would will find it.
Fewer, real findings
Because an engineer verifies each issue by hand, you do not receive a 200-page export where the three findings that matter are buried among theoretical warnings. You get a short list of things that are genuinely exploitable, ranked by what they would cost you, with a reproduction path your developer can follow. That is the difference between a document that sits in a folder and one your team actually fixes.
The right mix
In practice the two work together. Continuous scanning and monitoring keep watch between engagements and flag the obvious regressions the moment they appear. Periodic manual testing goes deep where the automation cannot. A good plan uses both and is honest about which is doing what.
Pricing
Ongoing website security services are billed as a monthly plan, tiered by how many sites you run and how much data is at stake. One-off testing and cleanup are quoted separately as fixed-price projects. Here is the shape of the managed plans.
| Plan | What’s covered | Response | Price |
|---|---|---|---|
| Essential | One site: firewall tuning, malware and file-integrity monitoring, monthly patch review, blacklist checks | Next business day | from €120/month |
| Business | Up to three sites: everything in Essential plus quarterly manual review, uptime and defacement alerts, priority support | Same day | from €180/month |
| Managed | Business-critical site or small estate: continuous monitoring, monthly manual checks, hardening changes included, 24/7 incident cover | 24/7, within hours | from €250/month |
| One-off hardening | Security configuration review and fixes for a single site, no ongoing plan | 3–5 working days | from €1,200 |
| Custom / large estate | Many sites or a full platform, scoped to your environment | on scoping | custom |
Every plan is fixed-price, quoted after a free 20-minute scoping call, and a retest is included whenever we ask you to fix something. Get a fixed quote
