Website Security in Cardiff
Securing Cardiff organisations' sites against how compromises actually occur. Almost none begin with someone attacking your code: they begin with a known vulnerability in a dependency nobody updated, a credential reused elsewhere and leaked, or an access key committed to a repository years ago.
Why this comes up
The problem
Nobody knows what the site depends on, several people share an administrator login, and the security position is whatever the hosting company includes by default.
What you get
What we deliver
- Dependency inventory with alerting, since known vulnerabilities are published daily
- Administrative access reduced and protected with multi-factor authentication
- Secrets moved out of code and rotated, including any already exposed
- Security headers and transport configuration set to current expectations
- A firewall in front of the site, filtering the automated traffic that never stops
- Logging that would let you reconstruct an incident afterwards

Working in Cardiff
Wales
Cardiff has a significant broadcast and media sector alongside a large public-sector presence, and Welsh-language provision is a genuine requirement on public-facing work here rather than a nice-to-have.
Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option.

Website Security in Cardiff — common questions
- How do sites actually get compromised?
- Through outdated dependencies with published vulnerabilities, and through credentials — reused, phished or leaked. Bespoke exploitation of your own code is rare by comparison. That is fortunate, because both common routes are addressable with unglamorous, inexpensive discipline.
- Is our host not handling this?
- They secure the infrastructure, not your application. Hosting protects the server, its network and often the platform, and leaves your dependencies, your code, your integrations and your users' credentials to you. Assuming otherwise is a common and consequential gap.
- What about secrets in code?
- Anything committed to a repository should be considered exposed, including in deleted commits and private repositories, which get shared and forked. Rotating keys that have ever been committed, and moving them into managed secret storage, closes a route that is trivially exploited.
- Why does logging matter?
- Because after an incident the first questions are when it started and what was accessed, and without logs the honest answer is that you do not know. That uncertainty forces you to assume the worst, which makes any data protection notification far more serious.
- Do you work with businesses across Cardiff?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Cardiff and the surrounding Cardiff area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Cardiff businesses do you usually work with?
- Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option. Beyond that we work across Media & Broadcasting, Financial Services, Public Sector, Higher Education and Sport.
- Do you cover the areas around Cardiff?
- Yes — we work throughout Wales, including Bristol, Swansea. Cardiff is an urban area of roughly 490,000+, and we take on work across the wider Cardiff region rather than the city boundary alone.
