support cybersecurity defenders and will provide trusted actors across society with access to defensive tools.<\/p>\n<p>The company\u2019s plan includes democratizing cyber defense, coordinating across government and industry, strengthening security around frontier cyber capabilities, preserving visibility and control in deployment, and enabling users to protect themselves.<\/p>\n<p>OpenAI said in its post that as AI reshapes cybersecurity, criminals are deploying the same capabilities as defenders.<\/p>\n<p>\u201cBuilding resilience in the Intelligence Age will require both working through democratic institutions and processes, and broadening access to the technologies that can help protect communities, critical systems and our national security,\u201d OpenAI said in the

capabilities of its\u00a0cybersecurity\u00a0product. The AI startup held an event in Washington, D.C., where it demonstrated a new model to officials from throughout the government and from various national security agencies.<\/p>\n<p>The company is taking a dual-track approach, making one version of its model more widely available with robust safeguards, and another more permissive version for cyber defenders through its Trusted Access program. This tactic will let more companies, like local water utilities, access advanced AI tools.<\/p>\n<p>OpenAI said April 14 that it plans to expand access to the Trusted Access for Cyber (TAC) program, which it introduced in February, to give cybersecurity professionals <a href=\"https:\/\/www.pymnts.com\/artificial-intelligence-2\/2026\/openai-expands-cybersecurity-program-before-deploying-new-models\/\">access to frontier models<\/a>.<\/p>\n<p>The company said it is scaling up TAC to thousands of verified individuals and hundreds of teams responsible for defending critical software.<\/p>\n<p>\u201cIn preparation for increasingly more capable models from OpenAI over the next few months, we are fine-tuning our models specifically to enable defensive cybersecurity use cases, starting today with a variant of GPT-5.4 trained to be cyber-permissive: GPT-5.4-Cyber,\u201d OpenAI said in an April 14\u00a0<a href=\"https:\/\/openai.com\/index\/scaling-trusted-access-for-cyber-defense\/\">blog post<\/a>.<\/p>\n\r\n<\/div>\r\n<script>\r\n\twindow.pymntsAllowedArticleCount = 2;\r\n\twindow.pymntsPostID = 3696620;\r\n<\/script>","protected":false},"excerpt":{"rendered":"<p>OpenAI\u00a0will start rolling out a frontier cybersecurity model called GPT-5.5-Cyber to \u201ccritical cyber defenders\u201d within days, CEO\u00a0Sam Altman\u00a0said\u00a0in\u00a0a Wednesday (April 29)\u00a0post\u00a0on X.
