But it\u2019s also given bad actors fresh opportunities to access sensitive data or manipulate automated systems. This deal underscores how frontier labs are scrambling to prove their technology can be used safely in critical business operations.<\/p>\n<p class=\"wp-block-paragraph\">Promptfoo was founded by Ian Webster and Michael D\u2019Angelo to develop tools that companies can use to test security vulnerabilities in LLMs, including an open-source interface and library. The company reports that its products are used by more than 25% of Fortune 500 companies.<\/p>\n<p class=\"wp-block-paragraph\">Promptfoo has raised just $23 million since its founding, and was valued at $86 million after its most recent round in July 2025, according to Pitchbook. OpenAI did not disclose the value of the transaction.<\/p>\n<p class=\"wp-block-paragraph\">OpenAI\u2019s post said Promptfoo\u2019s technology will allow its agent platform to perform automated red-teaming, evaluate agentic workflows for security concerns, and monitor activities for risks and compliance needs. The company also said it expects to continue building out Promptfoo\u2019s open-source offering.<\/p>\n<div class=\"wp-block-techcrunch-inline-cta\">\n<div class=\"inline-cta__wrapper\">\n<p>Techcrunch event<\/p>\n<div class=\"inline-cta__content\">\n<p>\n\t\t\t\t\t\t\t\t\t<span class=\"inline-cta__location\">San Francisco, CA<\/span><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"inline-cta__separator\">|<\/span><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"inline-cta__date\">October 13-15, 2026<\/span>\n\t\t\t\t\t\t\t<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n<\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/techcrunch.com\/2026\/03\/09\/openai-acquires-promptfoo-to-secure-its-ai-agents\/\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>OpenAI announced Monday it has&hellip; <\/p>\n","protected":false},"author":1,"featured_media":4461,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[249],"tags":[8473,703,441],"_links":{"self":[{"href":"https:\/\/microvibenews.com\/index.php?rest_route=\/wp\/v2\/posts\/27116"}],"collection":[{"href":"https:\/\/microvibenews.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/microvibenews.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/microvibenews.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/microvibenews.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=27116"}],"version-history":[{"count":0,"href":"https:\/\/microvibenews.com\/index.php?rest_route=\/wp\/v2\/posts\/27116\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/microvibenews.com\/index.php?rest_route=\/wp\/v2\/media\/4461"}],"wp:attachment":[{"href":"https:\/\/microvibenews.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=27116"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/microvibenews.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=27116"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/microvibenews.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=27116"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
