Priority fixes for commbank.com.au
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
TLS 1.3 negotiated
Observed: The TLS connection negotiated TLSv1.2.
Why it matters: TLS 1.3 removes legacy cipher suites and completes the handshake in fewer round trips, so it is both safer and faster for new connections.
What to do: Enable TLS 1.3 on your CDN or server. Keep TLS 1.2 available for older clients unless you have checked your audience.
On Cloudflare: Turn on TLS 1.3 under SSL/TLS > Edge Certificates.
86% of Banking & Finance peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
Priority 2 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for 600 seconds, short of the 30-day benchmark.
What to do: Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.
On Cloudflare: Use Cache Rules to set edge and browser TTLs for static file paths.
43% of Banking & Finance peers do this.
Priority 3 · Accelerate
Modern image formats in use
Observed: The homepage had 29 images and none used WebP or AVIF.
What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.
On Cloudflare: Cloudflare Polish can convert images to WebP.
37% of Banking & Finance peers do this.

Priority 4 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 14 external scripts without async or defer.
What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.
36% of Banking & Finance peers do this.
