BY THREAT [MAN-IN-THE-MIDDLE]

Counteract man-in-the-middle attacks

Build38 provides robust protection against MITM attacks. Our security strategy relies on the secure communication services within our in-app protection SDK, further bolstered by our cloud-based active app hardening.

How hackers do it

Hackers use man-in-the-middle (MITM) attacks to target mobile apps and devices by intercepting and potentially altering the communication between an app and external servers or systems.

By positioning themselves between the mobile device and its intended recipient, attackers can eavesdrop on sensitive data transmission, such as login credentials or payment information, without the user or app being aware. This allows them to steal information, inject malicious code, or manipulate data flow, compromising the confidentiality and integrity of an app’s communications and potentially opening the door to various forms of data theft or unauthorized access to sensitive systems.

How Build38 protects your mobile apps

Build38’s comprehensive approach to mobile app security safeguards the integrity of your application and protects it from man-in-the-middle attacks. We combine best-in-class mobile in-app protection with exclusive server-side capabilities, including always-on AI-powered active hardening, offering a unique, powerful defense against security threats.

Superior mobile app self-protection

The secure communications services within our SDK functions as the central defense mechanism against a range of network layer attacks, including man-in-the-middle attacks. Their primary purpose is to ensure the security of your application's sensitive data during transmission. Build38's protection operates on multiple levels, even in the face of an attacker's attempt to intercept and replay a message:

  • Certificate pinning is employed to prevent server impersonation.
  • Our SDK ensures secure configurations for TLS channel establishment, preventing downgrade attacks to insecure versions.
  • Our protection also extends beyond eavesdropping to include safeguarding against tampering.


Any attempts to interfere with your app’s communication flow are effectively thwarted.

Active hardening

We bolster mobile in-app protection with our unique cloud-based active hardening capabilities. These services enhance local app defense by individualizing every app instance through cryptographic keys, injecting a certificate into each instance, and consistently verifying device binding information. Furthermore, our active hardening server taps into a continuous stream of telemetry security data from all individual devices. This data is then fed into its real-time machine learning engine to generate actionable threat intelligence.
Threat Intelligence Portal

Our robust web interface allows every member of your team to monitor for security threats and get real-time alerts about suspected side-channel attacks. This allows them to take manual action as necessary, temporarily locking, then unlocking an app once a threat has been mitigated, or even permanently wiping it, if appropriate.

Attestation & Response

Using our intuitive no-code interface, your business team can effortlessly set up automated conditional triggers and rules, ensuring a fast and consistent response to future attacks based on well-defined, shared security policies.

Threat Intelligence & Response APIs

In addition to the simple no-code responses to threats enabled by our Attestation and Response modules, your back-end developers can utilize our powerful API to communicate security incidents to your back-end application logic, and program designated triggers and automated responses directly into your back-end system.
