An Intrusion Detection System (IDS) monitors traffic and alerts you to suspicious or malicious activity — it watches and warns, but doesn't stop traffic. An Intrusion Prevention System (IPS) sits inline and goes a step further: it detects and actively blocks or drops malicious traffic in real time. Many organisations run IPS for automatic blocking on critical paths and IDS-style monitoring more broadly — we help you decide the right mix.

Signature-based detection matches traffic against known attack patterns — fast and accurate for known threats. Behaviour/anomaly-based detection flags activity that deviates from normal — better at catching new or unknown attacks, but needs tuning to avoid false alarms. The strongest solutions combine both, plus current threat-intelligence feeds. We weigh detection quality and false-positive rates when matching you.

Network-based IDS/IPS (NIDS/NIPS) inspects traffic flowing across your network, catching attacks in transit. Host-based (HIDS/HIPS) runs on individual servers and endpoints, spotting file changes, privilege misuse and threats that never cross the network sensor. Most mature setups use both for layered coverage — we help you scope what's worth protecting at each layer.

Generally yes. A firewall controls what's allowed in and out at the perimeter, but threats still get through — via phishing, stolen credentials or an infected device — and then move laterally inside. IDS/IPS adds a layer that watches for and stops that internal malicious activity. Many next-gen firewalls include IPS, but dedicated detection, host coverage and SOC monitoring add depth, especially for larger or regulated environments.

Yes. CERT-In directions set expectations around security logging and incident reporting, PCI-DSS applies if you handle card data, the DPDP Act covers personal data, and sectors like banking have their own cyber frameworks — so detection, logging and timely response matter. Pricing ranges from licensing a product you run yourself to a fully managed monthly service with a 24×7 SOC.
