IDS vs IPS - What’s the Difference ?

When it comes to cybersecurity, two tools often confuse people: IDS (Intrusion Detection System) and IPS (Intrusion Prevention System). Both are powerful, but they don’t do the same job!

IDS (Intrusion Detection System):​

Monitors traffic & spots suspicious activity
Alerts you about threats but doesn’t block them
Think of it like a CCTV camera - it records, but doesn’t stop the intruder.

IPS (Intrusion Prevention System):​

Blocks malicious traffic in real time
Stops attacks before they reach your systems
Like a security guard - it watches AND stops the bad guys.

Quick Takeaway:​

IDS = Detection only
IPS = Detection + Prevention
Together, IDS + IPS = Strong Cyber Defense
Because in today’s world, Prevention is always better than Reaction.
