Protecting internal apps is
non-negotiable
Insider threats are real
Trusted employees and contractors can accidentally or intentionally expose vulnerabilities.
Internal doesn't mean invincible
Development, staging, and internal environments often skip the robust security hardening applied to production systems, leaving easy openings for attackers.
Compliance isn't optional
Frameworks like SOC 2 and ISO 27001 demand you protect all your assets - not just the ones facing the internet. Cutting corners internally can cost you dearly.

What is Beagle Security Cosmog?
Cosmog is your private network’s personal penetration tester. It works in your internal network, scanning for vulnerabilities across your internal web apps and APIs without needing public exposure.
No risky ports. No VPN headaches. No complicated setups.
Where Cosmog delivers value ?
Internal web applications
HR portals, finance dashboards, internal management tools. What's common among the lot? All of them contain sensitive information that attackers crave. Cosmog helps you proactively find and fix vulnerabilities in these systems — without ever needing to expose them to the public internet.
Staging and development environments
Security isn't just for production. Staging and development environments are often less protected but still hold critical data and early-stage code. Cosmog ensures you catch weaknesses early, before they become expensive problems in your live environment.
Internal APIs
Modern applications rely heavily on internal APIs to operate efficiently. If these private services are left untested, they create hidden attack paths. Cosmog scans and secures your internal APIs hosted on a private network to prevent silent breaches and data leaks.
“Beagle Security is an easy to use and cost effective way to proactively manage security risk for web applications. The team are super helpful. Highly recommend.”
