A strong website security score is more than a technical detail. It’s a signal to customers that you take their data seriously, a factor search engines and regulators increasingly weigh, and, for a cybersecurity-focused organisation, a direct reflection of your credibility.

That’s the spirit behind our ongoing partnership with the Cybersecurity Association of Singapore (CASL) on their website, cybersecurity.org.sg. As an organisation dedicated to advancing cybersecurity standards, CASL holds its own digital presence to the same high bar it champions for the industry. Together, we set out to make sure their website reflected that commitment at every level, from the front-end experience down to the underlying security configuration.

A Proactive Approach to Website Security

As part of our collaboration, we used Singapore’s Internet Hygiene Portal (IHP), a free security scanning tool from the Cyber Security Agency of Singapore, to benchmark the site against current best practices. This gave us a clear roadmap of where the site was already strong, and where we could raise the bar even further.

These are the kinds of enhancements that rarely show up to a site visitor. Pages load, forms work, everything looks the same on the surface. But strengthening these settings meant CASL’s website could match, at a technical level, the standards the organisation advocates for every day.

What Is a Website Security Score?

A website security score reflects how well a site follows current web security standards, including protocols like HSTS and TLS. Tools such as Singapore’s IHP scan a site’s configuration and highlight areas that could be strengthened.

What Is HSTS and Why Does It Matter?

HSTS (HTTP Strict Transport Security) ensures browsers only ever connect to a site over HTTPS, protecting against downgrade attacks and man-in-the-middle interception. It is a small setting with an outsized impact on how safely visitors can trust their connection to your site.

Why Move Away From TLS 1.0 and TLS 1.1?

Both protocols carry known security limitations and have been phased out across the industry. Standardising on modern TLS versions closes off attack paths that older protocols leave open, without requiring any change to how the site is built.

The Enhancements We Implemented

Working closely with CASL’s infrastructure team, we rolled out three targeted improvements:

  • Enabled HSTS, so every connection to the site is automatically upgraded to HTTPS.
  • Modernised the TLS configuration, retiring TLS 1.0 and TLS 1.1 in favour of current, supported protocol versions.
  • Reconfigured the TLS cipher suites, aligning the site with current best-practice encryption standards.

These are configuration-level enhancements rather than code rewrites, which meant we could roll them out smoothly, with zero disruption to the live site or its day-to-day operations.

The Outcome: A Perfect 100% Security Score

After the enhancements went live, CASL ran their site through the IHP scanner again. The result: a 100% security score.

For CASL, that number is more than a technical milestone. It’s proof, in a language regulators, partners, and cybersecurity professionals all understand, that the organisation’s own website reflects the standards it champions.

Why Your Website Security Score Matters Too

The same three areas we strengthened for CASL (HSTS, TLS protocols, and cipher suites) are worth a look on any business website. They rarely affect how a site looks or functions day to day. Your site still loads, forms still submit, checkout still works. But getting them right closes off some of the most common attack paths that modern security standards are designed to prevent.

Will Strengthening These Settings Affect My Website’s Design or Content?

No. These are server and configuration-level enhancements, not code or design changes, so they can typically be implemented without any visible disruption to the live site. As our work with CASL shows, it is fast, low-risk, and highly effective.

Test Your Own Website Security Score for Free

Curious where your site stands? Run a free scan through Singapore’s Internet Hygiene Portal (IHP), the same tool we used with CASL. Whatever it turns up, these are some of the most common (and most fixable) areas for improvement out there.
