Cybersecurity
Security reviews, hardening, patching and hacked-site clean-up for UK websites, shops and web apps.
At a glance
Almost nobody targets a small business website on purpose. Automated scanners crawl millions of sites a day looking for an out-of-date plug-in, a guessable admin password or a forgotten /old-site/ folder, and they break into whatever they find. What follows is rarely dramatic: spam pages for knock-off trainers appear in Google under your domain, mobile visitors get redirected to a scam, a card skimmer sits quietly in your checkout, or your email starts landing in spam because your server has been sending junk.
Our website security service is for UK businesses that want those risks dealt with by developers who can actually fix the code, not just hand over a PDF of findings. We look after WordPress sites, WooCommerce shops and custom web applications for businesses anywhere from Cornwall to Aberdeen, from our base in London.
The UK government’s Cyber Security Breaches Survey, published each year by DSIT, has consistently found that a large share of UK businesses (roughly four in ten or more in recent editions) report a breach or attack in the previous twelve months, with phishing by far the most common. Website compromises are a smaller slice, but they’re the slice we see most often, and nearly all of them come through the same few doors:
None of that needs expensive tools to fix. It needs someone to look, then a routine.
We’re developers, not a penetration-testing firm or a 24/7 security operations centre. If an insurer, a large client or a tender requires a formal penetration test, it should be done by an independent tester with recognised accreditation such as CREST. We’ll help you scope it so you don’t pay for testing you don’t need, then fix whatever the report finds. Our guide to website penetration testing in the UK explains what a test covers and roughly what it costs.
We also don’t do office IT: laptops, Microsoft 365 tenants, firewalls in your server cupboard. A managed IT provider is the right partner there, and we’re happy to work alongside them.
We start with read-only access to your site, hosting and DNS. Within a few days you get a short report: what we found, how serious each item is, and how long each fix takes.
Out-of-date software, exposed admin areas, stray backup files and missing off-site backups are usually sorted in the first session.
Most security is boring routine: updates every month, monitoring, and removing access when people leave. We set that up and, if you prefer, run it for you from a block of hours.
You get a one-page incident plan: who to call, how to take the site offline safely, how to restore, and when you may need to tell the ICO and your customers.
If your site collects personal data, UK GDPR requires appropriate security for it. A personal data breach that poses a risk to people generally has to be reported to the ICO within 72 hours of you becoming aware of it, so knowing quickly matters. Many suppliers to councils, the NHS and larger companies are also asked for Cyber Essentials, the government-backed scheme run by IASME. We can bring your website, hosting and related accounts up to the standard it expects; the certification itself is assessed by an approved certification body.
Security work is booked as hours that never expire. Straightforward WordPress sites are billed at our WordPress development rate of £50 an hour; custom applications at £60 an hour. All prices exclude VAT.
| Job | Typical time | Example price excl. VAT |
|---|---|---|
| Security review and hardening, typical WordPress site | 4 to 8 hours | 10 hours: £500 less 5 % = £475 |
| Hacked WordPress site clean-up | 4 to 12 hours | Depends on how far it has spread |
| Monthly patching and monitoring for a year | 1 to 2 hours a month | 20 hours: £1,000 less 15 % = £850 |
| Secure code review, custom Laravel or Node app | 10 to 20 hours | 20 hours at £60: £1,200 less 15 % = £1,020 |
Compare that with the cost of a hacked shop: lost sales while it’s offline, card details potentially exposed, and Google warning visitors away from your domain for days. A few hundred pounds of prevention is cheap.
Call us on 020 3918 3814. Don’t start deleting files or restoring old backups yet, because that can destroy the evidence of how they got in and leave the hole open. We’ll tell you what to do first, before any work is agreed.
Send us your website address and tell us what it runs on. We’ll tell you what we’d check and what it would cost. Contact us, or see how ongoing care fits with our infrastructure management service.
Common signs are unfamiliar pages in Google results for your domain, redirects to other sites on mobile, browser or Search Console warnings, admin users you don't recognise and a sudden drop in email deliverability. If you see any of these, contact us before changing anything.
WordPress core is well maintained. Most compromises come from out-of-date or poorly written plug-ins and weak passwords. Fewer plug-ins, monthly updates and two-factor authentication remove most of the risk.
We don't provide accredited penetration tests. For a formal test we recommend an independent CREST-accredited tester, and we can help scope it and fix the findings.
We can bring your website, hosting and related accounts up to the standard Cyber Essentials expects. The certification itself is assessed by an approved certification body.
Under UK GDPR, a personal data breach that poses a risk to people's rights and freedoms generally has to be reported to the ICO within 72 hours of becoming aware of it. Check the ICO's guidance or take legal advice for your situation.
Commonly 4 to 12 hours at £50 an hour excluding VAT, depending on how far the infection has spread and whether clean backups exist.
