Microsoft Edge security team employs a layered, data-driven defense strategy that focuses investments at key points along the kill-chain that attackers follow when exploiting vulnerabilities. Microsoft Edge in the Creators Update of Windows 10 leverages Integrity Guard (CIG) and Arbitrary Code Guard (ACG) to help mitigate arbitrary native code execution. Microsoft currently offers bug bounties of up to $15,000 USD for vulnerabilities found in Microsoft Edge and $200,000 for novel mitigation bypasses and defenses as part of our Mitigation Bypass and Defense Bounty programs.”]
