Why Upgrading from Umbraco 13 Should Be on Your Radar Now

🛡️ The Critical Importance of Upgrading from Umbraco 13
Plan early, stay secure, and protect your business with a future-proof website.

Published: June 11, 2025

If your website is currently running on Umbraco 13, now is the time to start planning your upgrade. With End of Life (EOL) set for December 14, 2026, this version of Umbraco will no longer receive updates, support, or security patches after that date.

While that deadline might feel distant, proactive planning is essential—not just for keeping your site functional and modern, but for protecting your business from security threats, maintaining compliance, and even validating your cybersecurity insurance.

Here’s why upgrading early is a smart business move.

🔐 Why Staying Up to Date Is a Security Must

Once Umbraco 13 hits EOL:

No more security patches will be released.
Attackers may exploit known vulnerabilities.
Compatibility issues with hosting and third-party services can emerge.

Staying on an unsupported CMS version significantly increases your cybersecurity risk. Hackers specifically target outdated platforms because they're easier to breach. With data protection laws tightening and threats growing more sophisticated, relying on outdated software is a gamble your business can’t afford.

✅ Cybersecurity Insurance & CMS Compliance

More companies are investing in cybersecurity insurance, and rightly so. But here’s what many overlook: Your eligibility and claims may depend on your tech stack being up to date.

Most insurers require:

Proof of regular software updates
Active security patching
Use of supported and maintained platforms

If your CMS is out of date, especially past its End of Life, you could risk policy invalidation or denied claims in the event of a breach. Insurers are tightening conditions, and using an unsupported CMS can be seen as a failure to take reasonable cybersecurity precautions.

Upgrading to the latest version of Umbraco is not just about site performance—it’s about protecting your entire digital operation and keeping your insurance coverage valid.

🚀 Benefits of Upgrading
