Imagine your house has a secret cookie jar. You hide it on the top shelf, behind a book, inside a locked cupboard. You think it’s safe - but what if someone sneaky figures out how to get in?
That’s where penetration testing comes in. It’s like hiring a professional cookie thief to try every trick in the book to break into your house. Why? So you can fix the weaknesses before the real burglars show up.
So, What Is Penetration Testing?
Penetration testing (or pen testing) is when ethical hackers - also called white hats - try to break into your systems just like a real attacker would. They use the same tools, tactics, and mindset, but they’re on your side.
At Teruza, we run these tests on everything from fintech apps and CRMs to mobile APIs and admin dashboards.
What Do They Actually Do?
Here’s the 5-year-old version:
Step 1 / Knock on all the doors and windows: Test every login form, API, port, and integration.
Step 2 / Jiggle the locks: Try weak passwords, outdated software, and misconfigured servers.
Step 3 / Peek inside: Look for secrets people forgot to hide - like access tokens or test admin panels.
Step 4 / Try to break stuff: Crash the app or send weird input to test validation and error handling.
Step 5 / Make a list: Document everything - including how serious each issue is and how to fix it.
Why You Need More Than Just Pen Testing
Penetration testing is just one part of modern cybersecurity. Our Teruza Security Packages include a full suite of tools to keep your systems safe:
✅ Penetration Testing (automated and manual)
✅ Code & Vulnerability Scanning
✅ Uptime & Downtime Monitoring
✅ Domain & SSL Expiry Checks
✅ Real-Time Protection (DDoS, brute-force, etc.)
✅ Resource Monitoring (CPU, RAM, Disk I/O)
✅ Human-readable Dashboards
✅ Exportable reports for your dev team
You don’t need to be technical to understand what’s going on. Our dashboard shows you everything in plain English, including charts for server load, RAM usage over time, and all discovered issues - ready to export and forward to your developers.
When Should You Book a Pen Test?
All our security packages include frequent scans - so if you're on a package, you're already protected on a regular basis.
But we also offer once-off penetration tests for clients who want a quick check before launching something new or undergoing a compliance audit.
What Does It Cost?
We offer a free package, but we strongly recommend starting with the Essential Package at R495 p/m, which includes a healthy mix of scanning, protection, and monitoring for most small to mid-sized apps.
