Best alternatives to ScanTower in 2026

KeyLeak Detector

A free scanner that catches a mistake almost every web team makes eventually: accidentally leaving a real API key or database password visible in a website's code where anyone can copy it.

KeySentry

A free tool that goes through a GitHub repository looking for accidentally-committed passwords, API keys, and sensitive files — the digital equivalent of checking your pockets before publishing.

Sucuri SiteCheck

Free website security check and malware scanner

Grego AI

A security firm that uses AI to hunt for serious bugs in smart contracts and blockchain code — the kind of flaw that, left unfound, can lead to millions of dollars stolen.

Stingrai

A penetration testing service that mixes AI-driven automated attacks with real, certified human hackers checking the results — so you get the speed of automation without just trusting a machine's word that a vulnerability is real.

ComplyJet

A service that helps a growing startup get its first security certification (like SOC 2) without hiring a dedicated compliance person — it automates the paperwork and connects you with real auditors, at roughly half what the bigger-name platforms charge.

Breachsense

A service that watches the dark corners of the internet — hacker forums, ransomware leak sites, malware logs — for your company's stolen passwords and data, and tells you within minutes if something shows up.

SpyCloud

An enterprise-scale service that collects stolen login data recovered from the dark web and uses it to automatically fix identity security problems before attackers can exploit them — across employees, customers, and vendors.

promptmap

A free tool that automatically tries to trick your own AI chatbot into misbehaving — leaking its instructions, saying something harmful, or ignoring its rules — so you find those weaknesses before a real user does.

KeyHunter

A fast, free command-line tool that searches GitHub for leaked API keys and then actually tests each one to confirm whether it still works — instead of just flagging text that looks like a key.

SecureSlate

A compliance service that pairs you with real, former auditors — not just software — to walk you through getting certified (SOC 2, ISO 27001, HIPAA), with the price agreed upfront so there's no surprise hourly billing.

General Analysis

An enterprise platform that continuously attacks and monitors your company's AI chatbots and agents in production — the way a security team would stress-test any other system — to catch manipulation attempts before they cause real damage.
