Casca Shield
Protection for Windows that tells you the truth.
Several detection engines work together on every file, a behaviour monitor stops attacks as they start, and the app always shows the real state of your PC — never a comforting guess.
Protected in three steps
No technical knowledge needed.

Everything a modern PC needs
-
Several engines, one verdict
ClamAV with millions of clamav.net signatures, YARA-X rules, Casca’s own signed signatures, heuristics, cloud intelligence and the Microsoft Defender engine.
-
Behaviour monitor
Every program is checked as it starts, and known attack behaviour — such as an Office document launching scripts — is stopped at once.
-
Ransomware shield
Mass changes to your documents raise an immediate alarm, and attempts to delete your backups are blocked.
-
Safe Banking
Before you pay, Casca Shield checks the site’s address and certificate, DNS and remote-control apps, then opens it in a private window.
-
Firewall and Anti-Hack
Windows Firewall managed for you, repeated sign-in attempts blocked, and webcam and microphone guarded.
-
Family and privacy
Screen time, bedtime and web filtering per child, plus alerts when your email appears in a data breach.
Honest by design
-
The real status, always
If protection isn’t running, the app says so — it never shows “protected” when it isn’t.
-
Your files stay on your PC
Only fingerprints are checked in the cloud, never your documents.
-
Signed updates
App and signature updates are digitally signed and verified before they are installed.
-
Your choice on false alarms
Restore anything you trust, exclude folders, and tell our lab with one click.
Common questions
Which Windows versions are supported?
Windows 10 (version 1809 or later) and Windows 11, 64-bit.
How many PCs can I protect?
It depends on the plan; you can see and remove your PCs in your Casca E-Connect account at any time.
Does Casca Shield slow my PC down?
Scanning runs in the background at low priority, and PC Tune-up helps keep startup fast. The ClamAV engine can be switched off on PCs with little memory.
Is there a VPN?
Secure VPN is coming soon to the Ultimate plan at no extra cost.
