Your Website Could Have Security Vulnerabilities You Don’t Know About
Building SaaS is easier than ever, but hidden security holes can put your users and data at risk. Even small mistakes can leave your app exposed to attackers.
Exposed API Keys: Sensitive keys accidentally included in public website code could allow unauthorized use of connected services.
Weak Security Settings: Missing protections and insecure configurations can leave your application more exposed to attacks.
Outdated Software: Vulnerable dependencies and old software versions can introduce known security risks.
Data Exposure: Weak access controls can allow users to access information they shouldn’t, even without special privileges.
Hidden Vulnerabilities: Security issues can remain unnoticed until a user, researcher, or attacker discovers them.
Why now
Holes get used faster than they get fixed
−7 days
Average time-to-exploit in Google’s M-Trends 2026 report. Below zero means attackers used a hole before its fix was out.
141
exploited vulnerabilities in eight months
Up from 127 in all of 2025.
95%
ran software with a known vulnerability
Most sites keep running old versions after a fix exists.
$100–500
Founders already pay for an audit
Many of them ask for fixes they can ship, and a scanner PDF doesn’t give them that.
Find Security Risks Before They Become Bigger Problems
Calmcomet helps you find security problems without hiring a security team. Just enter your website URL and get a free report showing what’s exposed, why it matters, and how to fix it.
-
Identify Potential Vulnerabilities
We review publicly accessible parts of your website for common security issues, exposed information, and risky configurations.
-
Understand Your Security Risks
Get clear explanations of the issues we identify, including their potential impact on your website and users.
-
Know What to Fix
Every reported finding comes with recommended next steps, so your developers know what to investigate and fix first.
What’s Included in Your Free Security Scan?
We look for common security risks that could leave your SaaS exposed.
An OpenAI key in the public JS bundle
Anyone who opens your site can copy it and spend on your account. Rotate it and move the call to your server.
The free scan checks externally visible information. Testing authentication, data access, injection, or other potentially intrusive vulnerabilities requires separate authorization.

Security Issue: What we found on your website.
Risk Level: High, Medium, or Low based on the available evidence.
Why It Matters: How the issue could affect your application or users.
Recommended Fix: Clear steps to investigate and address the issue.
Missing Security Header
Medium- Risk Level:
- Medium
- Issue:
- Your website does not return a recommended browser security header.
- Why It Matters:

- Recommended Fix:
- Review your web server or hosting configuration and add the appropriate security header.
Illustrative example only. Actual findings depend on the website being reviewed.
With your permission, we test deeper and send the fix
Sending test attacks needs the owner’s OK. So the deeper tests run on a site you’ve added and verified as yours, and never before.
-
Step 1
Add and verify your site.
- Shows us the site is yours
- No test attack runs before this
-
Step 2
We test it the way an attacker would.
- Data access and Supabase RLS
- IDOR, auth and injection
- Connect Supabase and GitHub if you want the full picture
-
Step 3
Get each fix as a pull request.
- One pull request per hole
- You approve every fix
-
Every deploy
Re-checked when you ship.
- On every deploy, not on a schedule
- A report you can share with your customers
How small SaaS teams check security today
Many small teams check nothing yet. Free passive scanners exist, like vibeward, VibeSafe and UNPWNED, and Lovable has one built in. We go further after the scan, with tests on your verified site, a fix you approve and a re-check on every deploy.

Common questions
Yes. The initial security scan is free. You’ll receive a report of identified potential vulnerabilities and recommended actions without paying.
Our goal is to email your security report within a few hours after you submit your website. Actual delivery may depend on review volume.
No. The report explains potential security issues in simple language, along with recommended steps your developer can take.
Yes. The initial checks are designed to work with publicly accessible websites, including applications built using Cursor, Lovable, Bolt, Replit, and traditional development tools.
The free review focuses on low-impact checks of publicly accessible information. We don’t perform intrusive security testing as part of the initial scan. Deeper testing requires verified ownership or explicit authorization.
No. An external scan can identify certain potential risks, but it cannot guarantee that your application is secure or discover every possible vulnerability. Some issues require authenticated access, code review, or authorized penetration testing.
The free report includes recommended fixes and next steps. Additional remediation services or deeper security testing may be offered separately.
No. You only need to provide your website URL and business email for the initial review. We won’t ask for passwords or private account access.
