What Is an Intrusion Detection & Prevention System?An intrusion detection and prevention system combines features from IDS and IPS to better detect and block malicious traffic, rather than just doing one of the two. IDPS products often have features like log analysis, alerts, and threat remediation to find anomalies and trends and help security teams stop threat actors. IDPS or IPS features often belong to a larger security suite or product offered by a vendor, serving as one module of many.
Top IDPS Solutions ComparedThe following comparison table compares our top IDPS products, including features like threat remediation as well as free trial and managed service availability:
OSSECBest Overall for Teams of Multiple Sizes

Check Point Quantum, the product family that includes Check Point&#;s next-gen firewalls and security gateways, also offers IPS that integrates with other members of the platform. Check Point IPS can detect and block DNS tunneling attempts, signature-less attacks, protocol misuse, and known CVEs. If you&#;re already a Check Point customer, the IPS fits particularly well; if you&#;re thinking about investing in an NGFW with built-in IPS, Quantum is also a strong option.
Best for Log Management & Reporting
SolarWinds Security Event Manager combines multiple security technologies, serving as a hub for insider threat management, incident response software, and log analytics, just to name a few. Consequently, it has plenty of IDPS capabilities to offer, but where SolarWinds SEM really shines is its log management and reporting capabilities: features include compliance reporting software and log analytics, making SEM a great choice for compliance-focused teams.
Best for Threat Intelligence
Trend Micro TippingPoint is a network security solution that helps guard against zero-day and known vulnerabilities with features like traffic scanning and threat blocking. Tipping Point integrates threat intelligence from its Digital Vaccine® Labs so your business has a clearer picture of threats across your infrastructure. We recommend Trend Micro if you&#;re looking for deep threat intelligence and cybersecurity capabilities.
Best for Managed Enterprise Services
Alert Logic is a managed detection and response platform that includes managed network IDS, as well as container security, threat detection, and vulnerability management. Alert Logic&#;s MDR platform can be deployed on-premises or as a cloud service. The managed security service has industry-leading dashboards and analytics to provide insights about organizations&#; network activity, threats, users, and configurations to improve proactive detection and response.
Our picks for top IDPS features include policy management, event alerts, reports, traffic analytics, and threat or incident remediation. Use this list of IDPS features as a benchmark as your team shops for potential products, and keep in mind a few specific features that your business most needs.
IDPS solutions should allow teams to manage security policies, configuring and overseeing them in a central management console. Policy management capabilities that are easy and straightforward to use will help your teams learn the product faster and configure it more successfully.
If you&#;re using a security product like IDPS, you&#;ll want to know immediately when a security event occurs. An IDPS solution should provide timely and clear alerts. Alerts should also be prioritized so your security team knows what to address or mitigate first.
It&#;s helpful for teams to share clear, understandable security data not only with each other but also with other employees, particularly leaders and executives. IDPS solutions should offer reporting so security personnel can make more informed, logical decisions from clearly presented data. Some products will offer both templates and customizable reports.
IDPS solutions should carefully analyze network traffic, detecting anomalies and determining when traffic doesn&#;t meet security policies. Traffic analysis can include packet inspection, which looks closely at the details of network packets and accepts or rejects them. This improves network security by filtering traffic based on your organization&#;s predefined policies.
Because IDPS includes prevention capabilities, not just threat detection, products should be capable of fixing or mitigating threats instead of just locating them. While products&#; remediation abilities will vary, they should assist teams in preventing and mitigating threats as quickly as possible once they&#;re found.
How We Evaluated IDPS SolutionsWe evaluated multiple IDPS products with a product scoring rubric, which had five weighted categories composed of subcriteria with their own weighting. Each product we reviewed received an overall score out of five, which was based on all the final subcriteria scores and weights. The six products that scored highest in the rubric made our final list, and the scores plus the products&#; overall capabilities helped us decide on their use cases.
Our most significant product criteria included major IDPS features and advanced features like threat quarantine. We also considered usability, which measured the availability of managed services and deployment options. Finally, we looked at pricing information and customer support details, including demos and support availability.
Intrusion detection and prevention systems &#;&#;protect IT systems from unauthorized access by monitoring the activities of users and looking for patterns that could indicate malicious behavior. IDPS can help protect teams from data theft, social engineering attacks, distributed denial-of-service attacks, and modification of sensitive data.
IDPS helps reduce technical downtime, mitigate breaches, and improve productivity by streamlining alerts and giving security teams more context about threats. While they need appropriate policy management and reporting to be effective and logical, they&#;re powerful tools once teams sufficiently configure and learn them.

IDS tools were built to detect malicious activity and log and send alerts. They&#;re not capable of preventing an attack, and the warnings they raise always require human intervention or an additional security system. IPS solutions respond based on predetermined criteria for types of attacks by blocking traffic and dropping malicious processes.
IPS tools may also lead to more false positives because they have inferior detection capabilities than IDS. However, IDPS solutions incorporate the strengths of both systems into one product or suite of products.
IDPS generally falls under two different types: host-based and network-based. Host-based IDPS is software deployed on the host that solely monitors traffic connecting to and from that host. It typically only protects a single, specific endpoint. In some cases, it may also scan system files stored on the host for unauthorized changes and processes running on the system.
Network-based IDPS is deployed in a location where it can monitor traffic for an entire network segment or subnet. Their functionality somewhat resembles firewalls, which can only prevent intrusions coming from outside the network and enforce access control lists (ACLs) between networks. NIDS was built to detect and alert potential malicious internal traffic moving laterally throughout a network; this makes it an excellent tool for a zero trust security framework.
Bottom Line: Use IDPS in Conjunction with Other SolutionsIDPS can help improve compliance and policy enforcement by enforcing policies that govern device connections to the network or internet, data transfer and storage for those devices, and data retention within systems.
While IDPS won&#;t be a sufficient standalone security solution for most enterprises, it&#;s a good product to have in the toolbox, especially if yours integrates with other tools, like NGFWs and endpoint detection and response. Use IDPS to support your security infrastructure as a whole, detecting intrusions and mitigating them more successfully with features like alerts, reports, and threat remediation.
