About Arnica

Arnica sells software that consolidates risks across SCA, AI SAST, IaC, secrets, licenses and low-reputation packages within a development environment. Arnica maintains an inventory of every identity, asset and risk in a development environment. Arnica scans every code change that developers push, including changes on feature branches. Arnica covers each new asset automatically, without needing integration into CI/CD pipelines. Arnica connects to systems like GitHub, GitLab, Azure DevOps and Bitbucket and analyzes commits, pull requests, branches and code changes in real time. Pipelineless security embeds security directly into a source control system instead of relying on CI/CD pipelines.[1][2][3][4][7][10]

Arnica injects a security policy directly into Copilot, Cursor and Claude Code at the point of generation. Arnie AI covers the lifecycle before agents write code, as they push it, and after it lands in a backlog. Arnie auto-injects secure coding instructions into Copilot, Cursor, Claude and Gemini. Agentic Rules Enforcer injects code rules directly into coding tools like Claude, Cursor and Copilot. Agentic Rules Enforcer prevents AI-generated risks including insecure authentication and authorization logic, hardcoded secrets, unsafe dependency usage, injection flaws, insecure cloud and infrastructure configurations, and violations of internal security or compliance standards. Arnie scans existing code for risks in production and identifies where agentic rules need to be applied.[3][5][6]

AI SAST combines deterministic static analysis with adaptive AI to detect, understand and fix vulnerabilities. Arnie's AI SAST combines traditional SAST precision with multi-agent AI that understands context and intent. AI SAST covers backlog code, new pushes and ongoing changes, unlike tools limited to pull requests. AI SAST covers risks including injection flaws, authentication and authorization issues, insecure data handling, secrets exposure, misconfigurations and logic flaws. Arnica AI SAST prioritizes risks based on severity, exploitability, code reachability and business context. Arnica provides AI-generated code risk mitigation suggestions for SAST and IaC findings.[5][7][8]

Arnica gives reachability guidance for Software Composition Analysis (SCA) vulnerabilities in code. Arnica provides patch, minor and major version fixes for SCA findings. Arnica runs every package upgrade path so developers can make package upgrade decisions based on security impact and operational risk. Arnica avoids sending an SCA finding to a developer when the finding has no upgrade path. Arnica uses threat intelligence in a threat detection engine to verify whether a secret is active. Arnica uses CVSS, EPSS and KEV severity scoring metrics to inform priority. Arnica classifies the most important repositories and branches and prioritizes risks within them.[2][8][10]

Developers receive a Slack or Teams notification from Arnica with actionable context. Arnica adds a security attestation to every pull request. Arnica auto-generates tickets in ticketing tools like Jira and Azure DevOps Boards when a risk is found. Arnica auto-closes tickets when a vulnerability is no longer detected in code. Developer dismissals become policies that take effect when security approves them org-wide or at the product level. Arnica uses behavioral signals such as code reviews, commits and risk mitigation activities to surface individuals already showing security leadership. When a security issue arises, Arnica tags the most relevant champion and notifies the champion through pull requests, Slack or Microsoft Teams.[3][8][11]

Arnica automatically tags Docker files with OCI-compliant labels, removing the need for engineers to manually track connections between repos and images. Arnica maps every image back to its repository, product and security champion. Arnica's container scanning applies function-level reachability analysis to vulnerabilities in the latest deployed images. Arnica exports PDF or CSV reports for licenses, dependencies and risks at the product level, and exports SBOM artifacts in CSV or CycloneDX. Arnica supports demonstrating policy adherence in compliance tools such as Drata or Auditboard. Arnica tracks the age of each risk with SLA timers that start automatically when risks enter production branches. N-able deployed Arnica across dozens of GitHub organizations containing thousands of repos.[2][3][4][6][9][12][13]
