Historical Environment Viewer - access issues

Date Released: Tuesday, August 11, 2020

Your browser may  advise you that there is a security risk associated with entering into the Historical Environment Viewer. For clarity on the cause of the warning, the application itself is hosted on a Web Server with an out of date operating system. This error will persist until the operating system is upgraded. The operating system has long been out of date, but browsers have only recently introduced the warning to alert users to out of date protocols and ciphers supported on that version of the operating system.

If you need to access the HEV just click on Advanced and proceed through.
