Container scans aren't enough. What if you could stop untrusted images before they hit your cluster?
Kyverno’s ImageValidatingPolicy does just that verify signatures, match image sources, support Cosign & keyless signing.

Last week while diving into Kyverno docs, I realized it’s not just about writing policies, it’s about what happens after.

@Denish3436 yes, Kyverno is very useful tool when Security is concern. I wrote a blog on that demonstrates how kyverno works, its architecture, etc

Pulled an image No errors Looks fine
But… is it signed? Trusted? Verified?
With Kyverno Image Verification, you can check:
✅Signature
✅Trusted registry
✅Attestations
If not?
Blocked. No surprises. No compromise.

You might think Kyverno only checks new YAMLs..
But it’s smarter than that.
🔐 Admission Controller
Stops bad configs at the gate.
🕵️♂️ Background Scanning
Finds old violations & fixes them.
New or old, Kyverno keeps your cluster clean.

🛠 ClusterPolicy = Does it all
✅ValidatingPolicy = Just clean validation
🔒ImageValidatingPolicy = No signature? No entry.
Easy to remember.
Your cluster will thank you.

Public cloud isn’t freedom—it’s lock-in.
You build there, and suddenly, you can’t leave.
With Qumulus, you deploy your cloud your way—bare metal, on-prem, AWS, or anywhere else.
🛠 Build once. 💨 Move freely. 🔓 Stay in control.
👉 Test Qumulus for free at qumulus.io

Setting up your own cloud shouldn't feel like a battle. ⛈️
Most developers spend more time fighting configs than building real solutions.
Qumulus removes the headaches so you can focus on what you do best—create.
No pain. Just power. → qumulus.io

Innovation thrives on freedom to test, fail, and try again.
But today, every cloud experiment comes with a heavy price tag — and it’s slowing developers down.
At Qumulus, we believe building and experimenting should never cost you your future.
