Why choose WordPress?

Mixd is trusted by the NHS, UK government, local authorities, emergency services and charities to develop fast, accessible websites that are crafted on the WordPress platform.

  • Security:

    The number of high profile brands that rely on WordPress is testament to its robustness. WordPress has a global community and a codebase which is open and constantly reviewed.

  • Open source:

    We save our clients hours by utilising an open source CMS that promotes flexibility. The collaborative nature of enterprise WordPress also avoids lock-ins which is advantageous for public services.

  • Scalability:

    WordPress comfortably handles exceptionally high levels of traffic, queries and content delivery for the world’s biggest publishers and is the ideal solution for public services.

  • Cost effective:

    Procurement decisions will often be awarded on a value for money basis. WordPress offers significant cost savings and value for both maintenance and development.


Is WordPress and open source software safe for enterprises?

WordPress currently powers around 43% of all websites on the internet. Unfortunately, this widespread use has led to several well-publicised security breaches, raising concerns about the platform’s security. Hackers aren’t getting in due to vulnerabilities in the WordPress software. Rather, most sites get hacked from entirely preventable issues, like not keeping things updated or using insecure passwords. At Mixd, we go to great lengths to bolster WordPress security. We employ specialised security tools including Cloudflare’s WAF and DDoS mitigation that effectively mitigate a vast majority of security challenges and maintain a high level of vigilance in safeguarding your data.

How do Mixd provide additional security for public sector organisations?

Mixd provides a stable, managed platform with enterprise-grade technology that automates threat detection and therefore limits the things customers need to worry about. We block attacks with continuous monitoring, automated updates, proactive threat detection and edge protection. In addition, our dedicated security team scans the risk and compliance landscape to ensure your site’s never compromised.

What is your process for updating WordPress?

Our team promptly deploys security patches and other protections to mitigate critical vulnerabilities. We alert all customers of upcoming WordPress updates and make sure you are on the latest version of the platform.
