Website Security for Agencies

Many agencies already charge a monthly care plan for updates and backups. Adding a real security tier to that plan turns a cost into a margin. We handle the work; you set the client price. The website security audit services become a paid engagement in your proposal rather than a favour you throw in and worry about.

Your clients are probably a mix of WordPress, Shopify, WooCommerce, a few custom builds and something inherited from a previous developer. Instead of learning the security quirks of each yourself, you get one partner who already knows them. As a cyber security agency working behind agencies, we are used to messy, real-world portfolios rather than tidy single-stack environments.

We run a baseline review on each site as it joins: outdated components, exposed files, weak logins, missing security headers. The quick fixes are applied, the larger ones flagged with a plan you can pass to the client. This first pass alone often surfaces two or three client sites that were quietly one plugin update away from trouble.

From there, monitoring runs continuously. When we detect a file change, an injection attempt or a component that just had a critical vulnerability disclosed, we act and log it. Your clients receive clean, branded reports that make your agency look like it has a serious security operation, because now it does.

The moment that matters most is when a client site gets hit. Instead of you fielding a panicked call and improvising, we step in: isolate the site, find the entry point, clean it, and restore it. You stay the trusted face of the response while an offensive-security team does the technical work behind you.

Because we already hold the baseline for every enrolled site, that response does not start from zero. We know what the clean state looked like, which components were present, and where the likely weak points were. That context is what turns a multi-day forensic guessing game into a contained fix, and it is the difference your client feels even if they never learn the detail.

If you reuse the same theme, plugin set or hosting configuration across clients, a single disclosed vulnerability can affect every one of them at once. Attackers know this and target agency-built sites specifically because compromising one pattern compromises many. Central patch tracking is how you get ahead of that instead of reacting to it site by site.

A client whose site gets defaced or blacklisted rarely blames the abstract world of cybercrime. They blame the agency that built and hosts the site. One bad incident, handled badly, can cost you a retainer and the referrals that came with it.

More client contracts now include security obligations, and more clients ask what happens if their site is breached. Having a real security partner, and being able to point to monitoring and an incident plan, changes that conversation from a liability you hope never surfaces into a service you charge for.

Almost every agency has them: a staging or demo subdomain left running after launch, unpatched, unmonitored, often with weak credentials. Attackers find these with automated scans and use them as a foothold onto the same server as live client sites. Enrolling and either securing or retiring them closes a door most agencies forget is open.

A premium plugin installed from a dubious source, or one whose developer stopped maintaining it, ships with either a backdoor or an unpatched hole. We flag these across the portfolio so you can swap them for something supported before they are exploited.

When the same admin login is reused across client sites, one leaked password compromises many. We audit for this on enrolment and push per-site credentials with multi-factor authentication on the accounts that matter.

We build on mainstream WAF and monitoring platforms, add our own detection rules, and reach for Burp Suite and manual testing when something needs investigating. Nothing is a black box you cannot audit or leave, which matters when the sites belong to your clients, not to us.

A client site that leaks personal data is a GDPR problem with reporting duties, and one that takes card payments falls under PCI DSS. Monitoring, patching and logging give you the technical measures those frameworks expect, and our reporting gives you the evidence to show a client, or their auditor, that security is being managed. We can issue an attestation letter for a specific client site when they need one.

We sign a mutual NDA covering your agency and, where needed, your clients. Access, logs and any recovered data live on encrypted storage and are handled only by the engineer assigned to your account.
