Protect AI vs TrojAI

Protect AI was a Seattle AI security company founded in 2022 by Ian Swanson (CEO), Daryan Dehghanpisheh and Badar Ahmed, who had previously worked at AWS, Oracle and DataScience.com. It raised $108.5 million: a $13.5 million seed round co-led by Acrew Capital and Boldstart Ventures (December 2022), a $35 million Series A led by Evolution Equity Partners (July 2023) and a $60 million Series B led by Evolution Equity Partners (August 2024), with Salesforce Ventures and Samsung among the investors. GeekWire reported 75 employees and offices in Seattle, Berlin and Bangalore in August 2024. Protect AI bought huntr, Rebuff, Laiyer AI and SydeLabs. Palo Alto Networks announced its intent to acquire Protect AI on April 28, 2025, the same day it launched Prisma AIRS, and completed the deal on July 22, 2025. It did not disclose the price; SiliconANGLE cited GeekWire sources putting it above $500 million. Ian Swanson joined Palo Alto as VP, Product, Prisma AIRS, and Prisma AIRS 2.0 (October 28, 2025) "completes the native integration" of Protect AI. Protect AI is no longer sold separately: protectai.com now redirects to the Prisma AIRS page, although some old blog posts are still online. Buyers should evaluate Prisma AIRS. **What it sold** Protect AI sold AI security, not governance. Guardian, built on its open-source ModelScan tool, scanned machine learning models for unsafe or malicious code and enforced policies on which models could be used. In October 2024 Hugging Face added the Guardian scanner to its Hub, and by April 2025 Protect AI had scanned 4.47 million model versions there. Recon tested AI applications before deployment with a library of 450 simulated attacks, and Layer filtered malicious prompts in production. Its earlier AI Radar product built a machine learning bill of materials. The huntr community, with more than 15,000 members in August 2024, reported AI and ML vulnerabilities. Palo Alto says the deal brought model scanning, posture management, AI red teaming, runtime protection and AI agent security to Prisma AIRS, but it doesn't map each Protect AI product to a Prisma AIRS module. **Open source** LLM Guard, Protect AI's open-source library for scanning prompts and responses, is archived: its README says the project and its Hugging Face models are no longer developed or maintained. **Frameworks** The Protect AI pages still online don't document a mapping to an AI framework, so this profile lists none. Prisma AIRS maps its AI Red Teaming attacks to the OWASP Top 10 for LLMs, MITRE ATLAS and NIST.

TrojAI is a Saint John, New Brunswick-based AI security company founded in 2019 by James Stewart and Stephen Goddard. The company provides an enterprise AI security platform with two core products: TrojAI Detect (pre-deployment model red teaming and vulnerability assessment) and TrojAI Defend (runtime AI firewall for AI applications and agents). In 2025, TrojAI extended Defend to cover MCP (Model Context Protocol) server governance, providing visibility and policy enforcement for agentic AI workflows. TrojAI serves primarily large enterprise customers in financial services and technology, helping them align with NIST, OWASP, MITRE ATLAS, and CSA frameworks. The company participated in Google's 2023 accelerator program for Canadian startups and was listed on the Vector Institute's '20 Canadian AI Startups to Watch.' TrojAI raised $5.75M in seed capital in April 2024 and maintains offices in Saint John, Fredericton, and Boston.
