How Kavach Scans Your Website for Malware and Phishing
- Kavach scans URLs on ports 80 and 443
- It uses a 256‑bit signature database updated daily
- Alerts arrive via email or webhook within seconds
- Free tier caps scans at a modest monthly limit
- The main trade‑off is occasional false positives
How does a cloud-based security scan work?
Kavach is a cloud‑based scanner that checks your website for malware, phishing hooks, and vulnerable code. It works by sending a lightweight request to your site’s public ports—usually 80 or 443—and comparing the response against a 256‑bit signature database that the team updates every day. According to the official docs (checked Sep 27, 2026), a single scan finishes in about 2.5 seconds on average. And if anything looks suspicious, Kavach fires an alert straight to your inbox or preferred webhook. So you get a clear, actionable report without having to install any software yourself.
Can Kavach detect phishing hooks automatically?
First, Kavach queues the URL you submit and resolves its DNS records. Then it fetches the homepage, CSS, and JavaScript files, looking for known malicious patterns. The engine checks each file against a list of 12,000 signatures that the security team curates. According to Kavach’s own documentation, the scanner can handle up to 500 URLs per hour on a single account. And if a page redirects, the tool follows up to three redirects before stopping, which helps avoid endless loops. So the result is a quick snapshot of what a casual visitor would see, flagged with any red‑lights the system spots.
Why perform a website vulnerability check?
Under the hood, Kavach relies on a combination of static analysis and heuristic scoring. Static analysis matches file hashes against the signature set, while heuristics look for suspicious code structures like eval‑based obfuscation. The team built the engine in Go, which gives it low latency and the ability to process roughly 1,200 requests per minute per core. But the real magic is the daily feed of threat intelligence from partner security firms, which adds fresh signatures within hours of a new exploit surfacing. So the tool stays current without you having to patch anything yourself.
How do I set up automated security alerts?
When a scan finishes, Kavach generates a concise report that highlights each flagged item, its severity, and a recommended fix. You can choose to receive the report by email, Slack webhook, or via the web dashboard. According to a user testimonial on the site, alerts typically arrive within 10 seconds of detection. And the dashboard groups findings by type—malware, phishing, or vulnerable code—so you can prioritize fixes quickly. So even a non‑technical site owner can understand what needs attention and act fast.
What are the limits and costs of using Kavach?
Kavach offers a free tier that lets you run up to 10 scans per month, which is enough for small blogs or hobby projects. Paid plans start at $29 per month for 1,000 scans, according to the pricing page (see Sep 27, 2026 snapshot). And each additional scan beyond your quota costs $0.03. The enterprise option includes unlimited scans, API access, and dedicated support, but it runs on a custom quote. So you can scale the service as your site grows, but the per‑scan cost can add up if you have a large inventory.
What are the main drawbacks of Kavach?
While Kavach is fast and easy to set up, it can produce false positives, especially on sites that heavily use client‑side rendering frameworks like React. A recent review on a tech forum noted that about 7% of scans flagged harmless code as suspicious. And because the tool only checks publicly reachable pages, it won’t catch vulnerabilities hidden behind authentication walls. So you’ll still need internal testing tools to cover those blind spots.
