Guardsquare Acquires Extended Threat Defense (XTD) Assets From Verimatrix

Earlier today, we entered into an agreement to purchase the Extended Threat Defense (XTD) technology and assets from Verimatrix.

We are incredibly excited to welcome both Verimatrix’s valued XTD customers and the dedicated team of engineers and personnel who have been instrumental in building, enhancing, and supporting the technology and its users.

We know that change raises questions. While the agreement is pending the completion of necessary regulatory checks over the next few weeks, we wanted to share some initial details and formally welcome everyone to Guardsquare.

Our top priority is ensuring a full and seamless continuity for all XTD customers while supporting our new employees during this transition.

As the creators of the open-source optimization tool, ProGuard, Guardsquare offers the most complete mobile application security platform on the market. Our platform spans automated testing, multi-layered protection, real-time threat monitoring, and app attestation. We are deeply committed to delivering the highest level of security in the most efficient way possible.

As Roel Caers, CEO of Guardsquare, shared in the press release announcing the acquisition:

“I am confident the addition of the technology developed by Verimatrix further reinforces our leading position in a constantly evolving market where innovation is key to supporting our customers in their quest to achieve the highest level of mobile app security.”

We eagerly look forward to officially working with the XTD customers and employees as soon as the acquisition has completed all necessary regulatory checks. The future of mobile application security is bright, and we are thrilled to be advancing it together.
