We connect your tools to your delivery pipeline, reduce alert noise, and put findings in front of the people who can fix them. GitHub Actions, GitLab CI, and Jenkins integration SAST, DAST, SCA, and secrets scanning rollout Finding triage, deduplication, and ownership routing Practical release gates and exception workflows Developer training and operational runbooks 03 AI Application & Agent Security Testing Find out whether untrusted input can make your AI application expose data or take an unauthorized action. We test chatbots, RAG applications, agents, and MCP integrations in the context of your actual permissions and workflows. Direct and indirect prompt-injection testing Sensitive-data exposure and tenant isolation checks RAG retrieval authorization and data access review MCP server and tool-permission assessment Hardening guidance and repeatable regression tests 04 GitHub Security Implementation Roll out GitHub Advanced Security with configuration your teams can maintain. We help implement GitHub Code Security and Secret Protection capabilities appropriate to your plan, repositories, and development workflow. CodeQL configuration, coverage, and alert tuning Secret scanning and push protection rollout Dependency review and Dependabot workflows GitHub Actions permissions and workflow hardening Repository rules, remediation ownership, and onboarding 05 Security Automation & AI Integration Reduce the manual work between detection and remediation. We build custom integrations and AI-assisted workflows that connect your security tools, engineering teams, and internal systems. Scanner, ticketing, chat, and cloud API integrations Vulnerability enrichment, prioritization, and routing AI-assisted triage with review before consequential actions Compliance evidence collection and reporting workflows Internal security assistants with scoped access and audit logs 06 Cloud Security Reviews & Remediation Understand your cloud exposure and put the fixes into practice. We review AWS and GCP environments, prioritize meaningful risks, and work with your team on hardening and infrastructure changes. Architecture, IAM, and configuration reviews Logging, data protection, and workload security Terraform review and hardening Prioritized findings and remediation planning Implementation support and validation 02 When to bring us in Built for teams with software to ship. ↗ You need a penetration test before a release or customer review. ↗ You are deploying an AI agent that can access business data or tools. ↗ You need GitHub security or CI/CD checks rolled out across repositories. ↗ Your tools produce findings, but your team needs a better way to prioritize. ↗ Your team needs help implementing fixes and maintaining security controls. 03 Ways to engage Start with a clear scope. Build from there. 01 Assess A defined application, AI workflow, cloud environment, or development pipeline. Receive evidence, priorities, and a clear remediation plan. 02 Implement Deploy integrations, tune security tools, harden permissions, and fix the issues alongside your engineering team. 03 Maintain Keep improving through ongoing tuning, vulnerability triage, regression testing, and security engineering support. Scope, deliverables, access, and pricing are agreed before work begins. GitHub features depend on your plan and licenses. Define the right engagement Tell us what you’re protecting and where you need clarity. Start a conversation ↗ ## Our Approach: Assess, Implement, Maintain | A3 Security Source: https://www.a3-security.com/approach.html How we work Rigorous where it counts. Practical from day one. Good security work changes decisions and behavior. Our approach is designed to surface meaningful risk, create shared understanding, and leave your organization stronger. Approach / A3 Security Evidence over noise 01 Our principles Better security starts with better signal. 01 Start with context We learn how your business, systems, and teams operate before deciding what to test or recommend. 02 Prove what matters We pursue evidence of real exposure and explain the conditions, impact, and likelihood behind every important finding. 03 Design for action Recommendations account for your architecture, capacity, and priorities—so remediation fits the way you actually work. 02 Engagement flow From uncertainty to a clear plan. A consistent four-part method keeps engagements focused while leaving room for the realities of your environment. 01 Frame the question Align on business drivers, scope, critical assets, known concerns, and what a useful outcome looks like. 02 Gather the evidence Review architecture and controls, test likely attack paths, and validate findings with careful human analysis. 03 Make risk legible Present concise, defensible findings for both technical teams and decision-makers, prioritized by actual impact. 04 Move through remediation Work alongside your team to answer questions, validate fixes, and turn the engagement into durable improvement. 03 What you receive Work products built to be used, not filed away. A Executive clarity A concise view of material risk, business impact, priorities, and the decisions leadership needs to make. B Technical evidence Reproducible findings, affected components, attack context, and direct guidance for engineering teams. C Implementation and ongoing support Prioritized fixes, working integrations, and handover documentation appropriate to your scope. Continue with tuning, triage, and regression testing when you need ongoing support. Get an outside view A focused conversation is the best place to begin.

A3 Security is an independent security engineering consultancy for software teams. We test applications and AI agents, integrate security tools into development workflows, and help implement practical fixes. About / A3 Security United States 01 Our point of view Security is strongest when it becomes part of how a company moves. We believe useful security is specific, understandable, and connected to the way work gets done. It should give leaders a confident view of risk and give technical teams a realistic path to reduce it. That belief shapes every A3 engagement: stay close to the problem, communicate without theater, and focus effort where it creates meaningful protection. 02 What defines us Small by design. Serious about the work. 01 Independent Our recommendations serve your goals. We are not tied to a tool vendor or a one-size-fits-all delivery model. 02 Experienced Senior practitioners stay close to the work and communicate directly with the people making and implementing decisions. 03 Collaborative We work with your team, share what we see, and make sure knowledge remains after the engagement ends. Working with your team Security expertise, wherever you work. We support organizations across the United States through focused remote collaboration and on-site work where it adds value.

You’ll get a clear proposal If there is a strong fit, we will outline the scope, approach, timing, and deliverables before work begins. 02 Common questions Useful context before you reach out. What kinds of organizations do you work with? We work best with growing, technology-enabled organizations that need experienced security support around cloud systems, applications, product delivery, or program decisions. Can an engagement be fully remote? Yes. Most assessments and advisory engagements can be delivered effectively through secure remote collaboration. On-site work can be planned when it materially improves the outcome. Do you only work with AWS? AWS is a core area of focus. Application security, secure delivery, tool advisory, and security program work can also span broader technology environments. Can you help after an assessment? Yes. Remediation guidance and validation are important parts of the work. We can stay involved to answer questions, review fixes, and help your team turn findings into lasting improvement. ## Careers at A3 Security | Future US Remote Opportunities Source: https://www.a3-security.com/careers.html Careers at A3 Security Bring your curiosity.
