Protect your brand with professional-grade protection

Application development teams face an ever-growing set of security threats as apps become more central to business and attackers grow in sophistication. These days, intellectual property theft is just the beginning - apps are also gateways to trade secret theft, customer/user data theft, and to identifying further attack vectors. Breaches in any of these areas can cause serious revenue, reputation, and brand damage. Sophisticated app dev organizations know that investing in app protection is good risk management.

App protection is a complex problem

Basic renaming obfuscation isn't enough. PreEmptive Protection Dotfuscator for .NET provides many layers of protection: multiple forms of obfuscation (renaming, string encryption, control flow, and more) plus active runtime checks (tamper, debug, root, and more). But it's not just about protection - we design and test all these layers to be sure that they won't break your app as the runtime platform evolves. We also constantly monitor the tools that attackers use and update our protection to counter their changes. Attacking an app with these layered protections becomes nearly impossible - each time an attacker tries to attack one layer of the protection, another layer is there, stopping them.

Trade-offs: time, quality, longevity

App protection initiatives are subject to the same constraints as any development project: scope, time, and ongoing support. Dotfuscator's professional-grade protection is easy to implement and comes with PreEmptive's world-class support. Imagine how you'll feel after Dotfuscator is implemented: secure in your protection, proud the implementation went so well, and confident that PreEmptive will be there for you in the future. Don't risk your app and your brand on second-rate protection. Invest in professional-grade protection with PreEmptive Protection Dotfuscator for .NET.
