Ship Faster. Ship Secure. Close Enterprise Deals.
Your team ships AI-generated code, deploys through automated pipelines, and serves hundreds of customers on shared infrastructure. We audit your entire SaaS stack - code, APIs, DevOps, cloud, and data isolation - and deliver a board-ready security report in 2 weeks. Enterprise deals close. Investors get confidence. Your customers stay safe.
Atlant Security is a technical SaaS security assessment firm, not a CPA-led audit practice or a compliance automation platform. We perform hands-on offensive testing of multi-tenant SaaS applications - tenant isolation, API authorization (BOLA), JWT and session security, cloud IAM, CI/CD pipelines, and secrets in Git history. Every finding maps to SOC 2, ISO 27001, and HIPAA controls so your compliance engagement goes faster. Founded in 2013 by a former Microsoft Security consultant. 200+ companies audited across 14 countries.
Every SaaS Security Audit Is Led by Alexander Sverdlov
Former Microsoft Security Consulting team member. CISSP, CEH, CHFI and Mandiant certified. Secured nuclear energy infrastructure at Emirates Nuclear Energy Corporation. Alexander has personally led 200+ security assessments across 14 countries since 2013. At Atlant Security, the senior consultant who scopes your SaaS audit is the same person who runs the manual testing and delivers your remediation plan - never handed to junior staff.
Connect on LinkedInSound Familiar?
Every week you wait is another week these risks compound.
Enterprise Deal Stuck?
Procurement sent a 200-question security questionnaire. You can't answer half of it. The deal sits in limbo while competitors move in.
AI-Generated Code Risks?
Your devs are shipping Copilot and ChatGPT code straight to production. Nobody's reviewing it for injection flaws, auth bypasses, or hardcoded secrets.
DevOps Pipeline Exposed?
A single compromised npm package injects code into your next production deploy. Your CI/CD pipeline is an attack surface nobody's auditing.
Customer Data Leaking?
Can one customer access another's data by changing an ID in the URL? One boundary failure exposes your entire customer database.
Secrets in Your Codebase?
Deleted Git commits still contain your production DB password and AWS keys. Git never forgets, even when you do.
SOC 2 Clock Ticking?
Your biggest client wants SOC 2 certification. Your auditor needs evidence you haven't built yet. Every week of delay is revenue lost.
We start from your architecture, not your front door
A scanner sees what is exposed to the internet. It cannot see that two tenants share a database role, that an internal service trusts a header it should not, or that your admin API was never in scope for anyone. We read the architecture first, then decide what is worth testing by hand.
You approve the test plan before anything is touched
Written scope, written method, written schedule, agreed against your release calendar. Nothing is tested that you have not signed off, nothing runs in a window you did not pick, and you know in advance which findings will need a code change rather than a config change.
Every tenant looks identical from outside
Isolation testing is about whether that holds from inside. We authenticate as one tenant and try to reach another: object references, exports, background jobs, webhooks, search indexes and cached responses. Cross-tenant access is the finding that ends enterprise deals, and it is almost never visible from the login page.
7 Attack Surfaces We Audit
Every SaaS platform has these attack surfaces. We test all of them manually.
Customer Data Isolation
Can one customer see another's data by changing an ID in the URL? We test every API endpoint to make sure your tenant boundaries are airtight.
AI & Vibecoding Security
Your team ships Copilot, Cursor, and ChatGPT-generated code daily. We find the injection flaws, auth bypasses, and hardcoded secrets that AI writes and humans miss.
API & Endpoint Security
We manually test every API for unauthorized data access, rate limiting bypass, GraphQL abuse, webhook tampering, and business logic flaws. Not a scanner report - real attack simulation.
DevOps & CI/CD Pipeline
Your deployment pipeline pushes code to production dozens of times a day. One compromised dependency or leaked build secret and an attacker owns your next release.
Cloud Infrastructure
AWS, Azure, GCP - we audit IAM roles, storage permissions, network configs, logging, and encryption. The misconfigurations your cloud provider won't flag for you.
Secrets & Credentials
Full Git history scan - even deleted commits still have your old AWS keys. Docker images, env vars, config files. Every credential you thought was gone, we find.
Auth, Login & Sessions
Token forgery, session hijacking, OAuth misconfigs, password reset flaws. If your login flow has a gap, an attacker will find it. We find it first.
How It Works: 4 Phases, 14 Days
From scoping call to board-ready report in two weeks, scheduled around your release calendar so the audit never blocks a ship date.
Scoping Call
30 min with your CTO. We map your architecture, identify crown jewels, deliver fixed-price proposal same day.
Data Collection
Screen-sharing sessions. Git clone. Cloud config review. API architecture walkthrough. Zero production access.
Testing & Analysis
Manual BOLA testing. Tenant isolation probing. JWT analysis. Cloud audit. Secrets scan. Critical findings reported immediately.
Report Delivery
Board-ready executive summary + engineering-ready technical details. CVSS scores. Reproduction steps. Sprint-ready fix plan.
What You Get
Including the evidence pack your enterprise customer's security team is asking for, written so you can forward it without editing it first.
Every deliverable is designed for a different audience - board, engineering, compliance.
Executive Summary
Board and investor-ready. Business impact, risk overview, maturity score.
Technical Findings
Every vulnerability with CVSS score, reproduction steps, and screenshots.
Remediation Plan
Sprint-ready. Prioritized by risk. Effort estimates for each fix.
Compliance Mapping
SOC 2, ISO 27001, HIPAA, GDPR control coverage for every finding.
Secrets Report
Every hardcoded credential found in Git history, Docker images, and configs.
Retesting
Fix the findings, we verify for free. One round of complimentary retesting.
A scanner cannot tell you which tenant owns the record
Automated tools grade what they recognise. They do not know your business logic, so they cannot know that an ID one digit away belongs to somebody else, or that an export endpoint ignores the tenant filter. That is the work below, and it is done by hand.
What Scanners Find
- Missing security headers
- Outdated libraries
- Open ports
- Default configurations
What We Find
- AI-generated code with injection flaws and auth bypasses shipping to production
- API endpoints where one customer can access every other customer's data
- Production database password sitting in a deleted Git commit from 2023
- CI/CD pipeline injectable through a single compromised npm dependency

What Our Clients Say
“Their professionalism, responsiveness, and strategic insight made a meaningful impact on our organization's security maturity. What impressed us most was their ability to translate complex technical risks into clear, actionable strategies.”
“We were 3 weeks into a stalled enterprise deal when Atlant found a BOLA vulnerability that would have let any user access every other customer's financial data. They reported it within 4 hours of finding it. We fixed it in 2 days, passed the security review, and closed the deal. The audit paid for itself 200x over.”
