Application servers
Supports Apache Tomcat, Apache TomEE, Glassfish, Jetty, Wildfly, IBM Websphere Application Server, Oracle WebLogic Server, JBoss Enterprise Application Platform.
Deep-rooted Java protection without a hit on performance.
Not all Java obfuscators are built the same. Stringer Java Obfuscator works at a deep level with the final app containers to protect your assets and code transparently. This helps to tamper proof your app.
Save time with instant integration
Stringer is simple to set up. Run it via the Command line or by using a plugin like Gradle or Maven - either way, protecting your application is a seamless process.
Protect on premises and avoid online risks
Don't expose your app to the unnecessary risks that come with cloud-based security solutions. Stringer operates offline in a safe environment you control.
Secure your app without slowing it down
Stringer's multi-layered security might be complex behind the scenes. but it doesn’t compromise performance. Your app retains its speed and responsiveness without any lag.
Features
Innovative protection mechanisms made to stop malicious threats.
Obfuscation, Encryption, and Virtualization
Stringer Java Obfuscator works at the native level of your application to harden its strings, classes, and metadata, plus app resources, assets, and internal data. It uses obfuscation, encryption, and virtualization techniques to stop attackers from stealing your IP or reverse engineering and modifying your app.
Anti-Tampering and Integrity Control
Stringer’s sophisticated encryption-based integrity controls involve calculating unique context-sensitive keys dynamically at the point of protection. Alongside runtime code checks, certificate checks, and file content checks, these controls stop attackers from modifying and exploiting your protected apps.
CryptoModule: White Box Cryptography Add-On
CryptoModule can be easily integrated with Stringer. It works as a software alternative to hardware-backed Trusted Execution Environments or Secure Enclaves, taking control of your app’s cryptographic processes automatically. Then it protects keys and sensitive data via white box cryptography and device binding.
Public Key Pinning and Certificate Transparency
Stringer enables protected apps to perform secure, client-side validation of public key certificates at the native level. This works to make sure that that the confidentiality and integrity of network communications are maintained. It also helps to stop man-in-the-middle attacks.
What's at stake?
-
Why you need advanced Java application security
In our digitally interconnected world, Java apps - both Standard Edition (SE) and Enterprise Edition (EE) - are vital for critical business operations. And because they handle sensitive data and interact with other secure services, they have become an attractive target for attacks.
-
Protection that acts as a trust enabler
Implement a secure execution environment like Stringer's Java Card Virtual Machine, and you ensure the integrity and confidentiality of sensitive operations. This enhanced protection helps to safeguard your app's core functionalities and maintains the trust you've built with users.
Stringer Java Obfuscator stops a wide range of threats. It's your shield against the damaging impact of attacks.
- reverse engineering
- vulnerabilities
- IP theft
- fraud
- malware injection
- repackaging
- runtime tampering
- sensitive data theft
How it works
Stringer’s protection layers work together to secure your app from dangerous attacks.
Code and resource hardening
Stringer started life as a java string obfuscator. But these days it does much more than that. Its code and resource hardening (obfuscation, encryption, virtualization, and isolation) makes your app's decompiled code almost impossible for a bad actor to understand. This first protection step is vital in stopping attackers from static reverse engineering - and decompiling and modifying - your app.
Secure runtime environment
Stringer can operate as a virtual trusted execution environment (vTEE), offering a safe, secure place for sensitive transactions to take place. This is incredibly important for applications - particularly in the financial and healthcare industries
Secure network communications
Application integrity
Stringer's integrity control stops attackers tampering with your app. It's a crucial defensive mechanism because without it hackers can inject malicious code, repackage, or clone your app. They can even remove other protection mechanisms. Stringer will detect it if the JAR has been modified - for example to illegally change the permissions of the app so that more people can access it than have paid to do so.
