What it sells: Phoenix Security

What Phoenix Purple does[1][2][5][7][8][9][14]
Phoenix Purple is an engineering-first application security platform. It connects directly to AI coding agents and delivers fixes as pull requests instead of tickets. Phoenix Purple runs deterministic SAST and SCA on a knowledge graph, adding reachability, a chainability map, and one-click assessment and remediation. Phoenix Purple is available in general availability.
What Phoenix Orange does[2][5]
Phoenix Orange answers what to fix and in what order. It aggregates every scanner into a single queue, strips out unreachable noise, attributes findings to the right team, and connects code-level findings to the cloud service where they run.
What Phoenix Green does[5]
Phoenix Green writes the fix as a pull request with the threat context already in the description. Risk tiering sets the path: safe changes move fast, moderate ones carry a review flag, and anything breaking or dangerous needs explicit human approval before it can merge.
What Purple Hook does[9]
Purple Hook is a local check that runs inside the AI coding assistant developers already use. It is generally available for Phoenix Purple customers.

About Phoenix Security

Phoenix Security is an Actionable ASPM platform that correlates vulnerabilities from code to cloud, turning fragmented findings into a single, prioritized remediation flow. Phoenix Security says it connects code to runtime, auto-assigns ownership, prioritizes reachable exposure, and uses AI agents to drive opt-in fixes and remediation campaigns, with humans in control. Phoenix Security turns high-effort vulnerability work into concrete remediation actions across code, containers, cloud and runtime.[5]

Phoenix Security describes a gap in which risk is measured at the board level but disconnected from actual fixes. Phoenix Security says multiple security tools only add to the complexity, hampering meaningful actions. Phoenix Security says keeping track of who is responsible for what is a nightmare when assets are uncorrelated and uncontextualized. Phoenix Security says teams need clarity and a strategic direction, driven by executives and actioned by developers.[6][13]

Phoenix Security ingests from 30+ scanners, including Snyk, Wiz, Qualys and Prisma. Phoenix ingests findings from every source, attributes ownership, prioritizes real exposure, and ships remediation, with AI agents and humans in control at every step. Phoenix Security maintains a living ownership graph so every issue routes to the right team, repo, and service rather than a shared queue. Phoenix Security prioritizes what is deployed, running, and reachable, enriched with threat intel and business context. Phoenix Security says AI agents generate minimum-impact fix plans and can open opt-in PRs, run campaigns, and measure risk reduction. Phoenix Security's Supply Chain Firewall enforces at npm/pip install time. MPI v3.1 provides 52-signal malware detection across 12 ecosystems. Phoenix Security's threat intelligence covers 300K+ CVE records and 6 proprietary scoring systems.[1]

Phoenix Purple is an engineering-first application security platform that connects directly to AI coding agents and delivers fixes as pull requests instead of tickets. Phoenix Security says Phoenix Purple cuts scanning token cost by 10 to 33 times through graph-native code intelligence. Phoenix Purple is available now in general availability. Phoenix Purple now runs deterministic SAST and SCA on a knowledge graph, adding reachability, a chainability map, and one-click assessment and remediation. Phoenix Purple connects every finding to code paths, runtime context, ownership and exploitability evidence, so security sees chains, not scanner output. Phoenix Security says every module feeds the same reachability engine, so SAST, SCA, IaC, containers and secrets land as validated findings. Phoenix Security says its graph gets built once, parsing seven languages and mapping call graphs, taint traces, entry points, and reachable paths. Phoenix Security says every PR diff is scanned against the graph, including the call-graph neighbors a change touches but does not directly edit. Phoenix Security uses a GitHub App for pipelineless pull-request scanning: install it, and the next PR gets scanned. Phoenix Security says developers can catch and fix issues as they write, right inside VS Code, Cursor, JetBrains and Windsurf. Phoenix connects to Claude Code, Cursor and MCP assistants, so agents can scan, query and fix in context. Autofix opens pull requests and labels them safe to merge or needs review. Exploit Hunt runs an adversarial three-persona pipeline inside Phoenix Purple's knowledge graph: attacker, skeptic, exploit developer. Purple Hook is a local check that runs inside the AI coding assistant developers already use, and it is generally available for Phoenix Purple customers.[1][5][7][8][9]

Phoenix Orange answers what to fix and in what order, aggregates every scanner into a single queue, strips out unreachable noise, attributes findings to the right team, and connects code-level findings to the cloud service where they run. Phoenix Green writes the fix as a pull request with the threat context already in the description. Risk tiering sets the path: safe changes move fast, moderate ones carry a review flag, and anything breaking or dangerous needs explicit human approval before it can merge. Phoenix Security says a person always decides what ships. Phoenix Security reports a 98% reduction in container vulnerabilities at ClearBank, $6.3M in developer time saved at Bazaarvoice, and a 78% reduction in active container vulnerabilities plus $1.95M saved at IAS.[5]

Phoenix Security offers a free risk-based application security management and prioritization platform. Phoenix Security offers a plan for growing and medium enterprises that want to control application security and manage vulnerabilities with a concise security team. Phoenix Security offers a plan for larger teams needing more analysis and workflow, actionable insights and monetization to prioritize millions of vulnerabilities in a few clicks. Phoenix Security's larger-team plan includes Dedicated Hosting and Bring Your Own Encryption Key. Phoenix Security offers a yearly contract with an option to pay monthly. Phoenix Security offers a Startup package for any small, growing business. Phoenix Security lets organisations start on the freemium licence if the organisation qualifies, and move to a different tier at a later date. Phoenix Security lets organisations create resolution tickets in platforms like Jira and ADO.[1][10][11]
