PreEmptive

PreEmptive provides application protection and hardening solutions for .NET, MAUI, Java, and Android applications. The company's technology focuses on protecting applications from reverse engineering, tampering, and data theft through obfuscation, encryption, root detection, shielding, and tamper-proofing techniques. Their solutions are embedded directly into applications without requiring agents or changes to end-user devices or networks. Founded in 1996, PreEmptive has been integrated into Visual Studio since 2003 and is subject to Microsoft's regression tests, code audits, and security reviews. The company serves over 5,000 corporate clients and 20,000 users worldwide across desktop, mobile, cloud, and IoT platforms. Their client base includes financial institutions, healthcare organizations, government agencies, telecommunications companies, and technology firms. PreEmptive's protection approach uses multiple layers including rename obfuscation, control flow obfuscation, pattern transformation, and dummy code insertions to make code difficult to interpret and reverse engineer. The solutions help organizations protect intellectual property, prevent revenue loss, maintain compliance with regulations, and defend against fraud and unauthorized access. PreEmptive was acquired by Idera, Inc. in 2021 and is now part of Sembi, a portfolio of testing and security software brands.
