OUR TRUSTED CUSTOMERS

The Risk

Your website isn’t just a digital storefront — it’s a living ecosystem of third-party scripts, integrations, and embedded code. Every external dependency introduces invisible risk. When those risks go unchecked, the pain multiplies — across compliance, finances, and reputation.

1. Silent Entry Points

2. Compliance Exposure

3. Trust Erosion = Revenue Loss

Every incident erodes customer trust.
Every exfiltrated record amplifies financial and reputational damage.

Studies show:

60% of users abandon a brand after one data breach.
The average cost per breached record exceeds $165 (IBM, 2024).
Reputation recovery often takes 2–3 years — if it happens at all.

1. Silent Entry Points

Modern web apps load dozens of third-party JavaScript resources. Attackers exploit these dependencies to inject malicious code, skim payment data, or exfiltrate sensitive information — often without triggering traditional security alerts.

→ 38% of web breaches now originate from compromised third-party scripts.

2. Compliance Exposure

3. Trust Erosion = Revenue Loss

Detect threats before damage

Jsmon finds threats in the application code layer. Be it a vulnerable client-side functions, third party dependency, or misconfigured cloud assets.

Search and manage the assets

Gives you an overview of your organization's assets linked to dependencies, vulnerabilities, third party risks, APIs, etc.

Alerts at the first second

Alerting via JIRA, Linear, Slack, etc. at the moment vulnerability is detected. Configurable alert rules - what to monitor, when to monitor.

Tried @jsmonsh by @3ncOd3dGuY today, and it's absolutely worth it! Just entered a domain, and within minutes, I had all the API paths, keys, tokens, and even S3 bugs in my dashboard. This tool is a game-changer! A must try!"

JSMon uncovered hidden API endpoints that others missed, helping me land two bounties. If you're into bug hunting, this tool is a game-changer. Highly recommend checking it out!
Mohsin Khan
Yaay! I got a bounty using @jsmonsh. I tried out the free plan, and it detected an API key exposure from the js file. I then exploited it using the Keyhacks repo from GitHub. Great service! Much appreciated.
