The three-places framing (app pages, API endpoints, DB) is the right mental model — most scanners only check the frontend guard and miss the API and row-level gaps. When the 1-prompt fix runs, does it patch the actual authz logic in my codebase (and where: API middleware vs a DB row-level policy), or does it just flag and hand me a diff to apply myself? And to exercise authenticated endpoints for broken access control, how does it get in without me handing over production credentials?
@hi_i_am_mimo
Great breakdown, and you're right. Frontend guards get all the attention while API and row-level gaps leak the real data.
On fixes: you stay in control. The Fix Agent doesn't push code behind your back. Each finding comes with a one-prompt fix you run in your own code agent, like "Fix Critical" or "Fix #2". The fix targets where the flaw actually lives, so an unprotected endpoint gets patched in your API authz logic, and a row-level gap gets fixed at the data layer. You review before anything ships. Fast, but never blind.
On access: no production credentials needed in most cases. Our agents sign up their own test accounts, just like a real user would. Then they test what those accounts can and cannot reach across UI, API, and data. You only provide accounts if your app doesn't support sign-up, like invite-only apps. And since we skip injection attacks entirely, testing is production-safe.
Drift detection keeps it going as your app changes, so coverage never goes stale.

@intesar_mohammed1 That production-safe angle (self-signup test accounts, skipping injection) is what makes it actually runnable against a live app. One boundary question: self-signup covers a single account privilege escalation, but the nastier gaps are cross-tenant — org A reading org B rows via IDOR. Does the agent provision multiple accounts across separate tenants to test that horizontally, or is it scoped to what one signed-up account can reach?
@hi_i_am_mimo
Great question, and you're right that cross-tenant gaps are the nastiest ones. Here's how we cover the full boundary map:
Cross-tenant: Our agents provision OrgA and OrgB as separate tenants, then check if one org can read or change the other's data. IDOR, BOLA, cross-org access, all tested horizontally.
Same tenant: Inside each org, we test if User1 can reach User2's private data. Think one teammate reading another's records they shouldn't see.
Roles: We provision Role1 through RoleN and test every role against every action and data object. That covers vertical privilege escalation, like a viewer doing admin actions.
Drift: Apps change fast, so we keep testing as you ship. A new gap in any of these areas gets caught, not left sitting unnoticed.
Every issue comes with proof of the exact request that crossed the boundary, in a pentest-style report.
Congratulations to the whole @Perfai Security team!! In the AI era, auth and access control issues have become an epidemic, and they're often some of the hardest vulnerabilities to catch before they reach production.
We're actually using Perfai ourselves to help ensure the Dashboard for @Wristband's multi-tenant auth platform is configured correctly and that tenant isolation and authorization rules behave as expected. It's been a great addition to our development process, and seeing it in action has given me an even greater appreciation for what the team is building.
Having personally watched the evolution of this platform, I'm especially excited to see this launch. Huge congratulations to @intesar_mohammed1 and the entire team. Beyond building a great product, they're genuinely friendly people and a pleasure to work with. Looking forward to seeing where Perfai goes from here! 🚀
@jim_verducci
Thank you so much! This comment made our day.
Wristband is exactly the kind of use case we love: a multi-tenant auth platform where tenant isolation has to be right, every time. Watching your team use Perfai to prove authorization rules behave as expected, across every update, is the product working exactly as we dreamed. Auth platforms hold everyone else's front door keys, so the bar is highest there.
And the kind words about the team mean just as much as the product praise. Working with you all has been a pleasure for us too.

Vibe coding made building apps 10x faster, but security has become the biggest blind spot. Love that you're solving this with a single prompt approach. This could save builders countless hours of manual audits. Congrats on the launch
@suryansh_tiwari2 thank you!! 🙏 and you framed it exactly right: vibe coding made building 10x faster, but nothing made to secure at that same speed. That's a gap we close, and aim to improve. Those "countless hours of manual audits" are the real cost... enumerating 6,000+ access controls across UI, API, and DB by-hand takes a pentest team weeks, but our agents run the same matrix autonomously in minutes.
Since EverTutor's likely handling real student data, I'd love for you to try it out. You can sign up free or get 50% off on the pro plan at perfai.ai
@suryansh_tiwari2
Thank you! You said it perfectly. Building got 10x faster, but security didn't keep up. That gap is where all the trouble lives.
The wild part is most builders don't even know what they're missing. Gartner reports access control issues drive about half of all breaches, and those bugs are invisible when you're just clicking around your app. That's why we made testing as easy as building: paste your URL, our agents do the rest, and every finding comes with a one-prompt fix like "Fix Critical".
No manual audits, no thousands spent on pentests, and drift detection keeps you covered as your app grows.

The “paste your app URL” workflow is appealing because it removes a lot of the friction around security testing. I’m wondering how you decide which vulnerabilities to prioritize first—do you rank them by severity, exploitability, or something else?
@amjad_shaik Great question... The short version is we rank findings by proven impact, not theoretical severity.
Every finding is exploit verified before it reaches you, so the list starts with what's actually exploitable.
From there we weigh things like blast radius, which roles or tenants are affected and how much data is exposed, along with CVSS severity and estimated bug bounty value. A confirmed cross tenant data leak will always rank above a low risk theoretical finding.
Every issue includes the severity, OWASP category, CVSS score, CWE, reproduction steps, and the evidence behind it.. we want you to see proof, not probability.
Give it a shot, it's free.. perfai.ai, and you'll see the ranked report for your own app.
@atefa7med Thanks for the detailed explanation. I like the idea of ranking exploit-verified findings over theoretical risk. That feels much more useful for teams that need to decide what to fix first.
@amjad_shaik
Thanks! Removing friction was the whole point. Security testing shouldn't need a setup project.
On prioritization: we rank by severity first, with critical issues at the top. But severity isn't just a label. It reflects real impact, like whether the flaw actively leaks data, what kind of data is exposed, and how easy it is to reach. An open door to customer records ranks way above a minor gap in a low-value page.
Active data leaks get flagged loudest, since those are already hurting you. Each finding also maps to standards like OWASP and CWE, so your team knows exactly what it is and why it matters.
The report groups everything so you fix the scary stuff first instead of drowning in a flat list of alerts.

Most of my codebase was written with AI coding agents, so security is honestly the thing I think about the most. Product logic I can verify just by using the app, but auth edge cases never show up that way. One question, when the fix agent ships a patch, do I get to review it before it lands? A one prompt fix sounds great until it touches something load bearing :) Congrats on the launch!
@henry_s_jung Yes, exactly. You always review the fix before anything changes.
When the Fix Agent generates a patch, it doesn't touch your code directly. It sends the suggested fix, along with the full vulnerability context, to the AI coding assistant you're already using (Cursor, Claude Code, Replit, and others).
You review it, make any changes you want, and decide whether to apply it. Nothing changes until you approve it.
Perfai then re-runs the exact exploit to confirm the issue is actually closed. It's designed to give you the speed of AI generated fixes while keeping you in control.

@henry_s_jung
Thank you! And you nailed the exact problem: you can verify product logic by clicking around, but auth edge cases hide until someone hunts for them.
Great question on the Fix Agent. Yes, you review before anything lands. The agent generates the patch and shows you exactly what it changes and why, but you stay in control of what ships. Nothing touches your app behind your back. We agree a one-prompt fix should never blindside something load bearing :)
So the flow is: we find the issue, show you the exact request chain that triggered it, generate the fix, and you approve it. Fast, but never reckless.

@intesar_mohammed1 That's the right call, showing the patch before it ships is exactly what I'd want. Congrats again on the launch, and good luck with the rest of the week. Might run my own app through it before Tuesday :)
@henry_s_jung
Thank you! And yes, please do run your app through it before Tuesday. Just paste your URL at perfai.ai and the free tier will get you a full test with a pentest-style report.

@ridhwikvinod You're pointing at the part we care about most. Verification isn't an afterthought, it's a core part of the workflow.
Once a fix is applied, Perfai re-runs the original exploit to make sure that specific issue is actually gone. We don't consider a vulnerability fixed until the attack no longer works.
We also re-map and re-test the application after every change. That's important because an AI generated fix can solve one problem while unintentionally introducing another. The re-test is there to catch exactly that.
The end result is a clear verdict for every finding, backed by proof instead of assumptions.
Feel free to try it.. it's free at perfai.ai
@ridhwikvinod
Thank you! And great point. An AI fix without verification is just more vibe code.
Yes, we re-test after every fix. The agent re-runs the exact request chain that triggered the vulnerability to confirm it's closed. And since re-scans only need your app URL, running a full scan after patching is one click, so you can confirm the fix didn't open a new hole somewhere else.
You also review every fix before it ships. The agent shows you what it changes and why, so nothing load bearing gets touched blind.
That's the loop: find, fix, verify. Not just find and hope.

Qutub, that little knot of worry right after you ship something fast is so familiar. Having something quietly watching your back so you can actually breathe afterward feels genuinely kind to the people building.
@benjamin_riou
Thank you for putting it that way. That knot of worry is exactly what we're trying to untie.
Shipping fast should feel exciting, not scary. But so many builders hit publish and then lie awake wondering what they missed. Nobody should need a security team just to breathe after launch. That's the whole reason Perfai exists: something quietly watching your back, testing every update, catching the gaps before anyone else does.
Comments like this remind us why we build. Thank you.
If you ever ship something, the free tier at perfai.ai is there, with a full pentest-style report and drift detection as your app grows. We're giving away 50% discount codes for the launch too. And if you need extra credits or help onboarding, just reach out. Happy to help!
This is a very timely problem. Vibe-coded apps can get to “working demo” incredibly fast, but access control and production security are exactly where small mistakes can become painful later.
I like the idea of making security checks feel as lightweight as pasting in a URL instead of requiring a full security workflow. When Perfai finds a live vulnerability, how much of the fix is automated versus guided for the developer to review and apply?
@klein1
Great question! If you built with Replit, Lovable, or any AI coding tool, just run "Fix all Perfai issues" and it will instantly fix them. Each finding comes with the exact context your coding agent needs to apply the fix.
For everything else, our Fix Agent writes a suggested fix for each issue, with the permission gap explained and proof of how we exploited it. Your developer reviews and applies it. We keep a human in the loop on purpose, since access control changes can break real user flows if applied blindly.
Every finding ships in a pentest-style report, and we run drift detection too, so if a new gap shows up as your app changes, you'll catch it.

Great concept. My team runs into this problem consistently. Even with AI guardrails and instructions, we have to spend valuable hours testing for vulnerabilities.
@zohaib_akmal
Thank you! Your team's experience is exactly why we built this. AI guardrails help, but they can't replace real testing, and doing it by hand eats hours.
Perfai Security does that testing for you. Just enter your app URL. Our agents sign up their own test accounts, then test thousands of permission combos across roles and actions. You get a pentest-style report with proof for every issue. We also run drift detection, so new gaps get caught as your app changes.

Great idea! Quick question: how do we ensure this fix doesn't break anything or cause a regression in the application?
@maaz_b_tariq_shaikh
Great question! This is exactly why we keep a human in the loop. Perfai suggests the fix, but your team reviews and applies it. Access control changes can break real user flows if applied blindly, so we never push changes to your app ourselves.
Each finding comes with proof of how we exploited it, so your developer knows exactly what to fix and why. After you apply the fix, just re-run the test. Perfai verifies the issue is gone and that your other permission checks still pass. Our drift detection also keeps testing as your app changes, so if a fix causes a new gap later, you'll catch it fast.
