About Hexiosec

The NCSC’s Web Check and Mail Check services are being retired on 31 March 2026. Hexiosec ASM provides a straightforward way to maintain visibility of your website and email security as part of a broader Attack Surface Management capability.

Hexiosec was selected as one of just ten providers to contribute practical EASM experience to the NCSC's Active Cyber Defence (ACD) 2.0 External Attack Surface Management (EASM) activity. The resulting work informed the NCSC's EASM buyer's guide, and Hexiosec ASM aligns strongly with the core capabilities it recommends you consider when selecting an EASM product.
