SWGfL Internet Filtering – Essential Change Required by 28 February

To ensure that RM SafetyNet continues to intercept and filter inappropriate content, you must deploy a new security certificate to all computers and devices that browse via an RM SafetyNet filtered connection. The old version must also be removed.


RM have provided clear instructions on how to do this at www.rm.com/updategooglessl and set up a dedicated helpdesk for installing the new certificate. This team will be calling all RM SafetyNet customers to talk you through this update. If required, they will arrange a suitable time for an engineer to talk you through the process and answer any queries you may have.

If you would like to speak to a support representative about this upgrade, please call the dedicated RM helpdesk on 01235 826263.

Why is this needed?

At the start of 2015, RM introduced ‘SSL interception’ functionality to RM SafetyNet. This gave RM the ability to successfully intercept and filter inappropriate search results, following Google’s decision to implement HTTP encryption for Google searches.
Since then, Google and other major web and cloud service providers have announced plans to stop allowing access to sites using security certificates signed using the older SHA-1 hash algorithm.

In order to future-proof RM SafetyNet and support future changes to browser security requirements, RM is issuing a new trusted root certificate which uses a stronger SHA-384 hash algorithm. This stronger algorithm will reduce the need to issue further root certificate updates in the future.

If you have any queries please contact your Technical Support or the dedicated RM helpdesk (01235 826263)
