Wire-speed packet capture/transmission using commodity hardware with PF_RING. Zero-Copy packet distribution across threads, applications, Virtual Machines. Libpcap support for seamless integration with legacy applications.
10 Gbit and above lossless network traffic recording with n2disk. Industry standard PCAP file format. On-the-fly indexing to quickly retrieve interesting packets using fast-BPF and time interval. Precise traffic replay with disk2n.
nProbe: extensible NetFlow v5/v9/IPFIX probe with plugins support for L7 content inspection. nProbe Cento: up to 100 Gbit NetFlow, traffic classification, and packet shunting for IDS/packet-to-disk acceleration.
High-speed web-based traffic analysis and flow collection using ntopng. Persistent traffic statistics in RRD format. Layer 7 analysis by leveraging on nDPI, an Open Source DPI framework.
Traditionally nProbe is used as a host-based network monitoring probe able to produce “augmented” flow records including performance monitoring, security and visibility information. We have a common vision with Kentik of how network instrumentation needs to evolve beyond “just” bytes … Continue reading →
Earlier this year we have held a ntop meetup in USA. Now we want to invite you to attend the ntop users meeting that will take place on October 17th (2 PM-5 PM), during the SharkFest Europe 2016 conference. The idea … Continue reading →
Since the introduction of nProbe Cento, we receive periodically emails of users wondering what are the differences between these two applications. This post is to clarify the differences, and better position them. The nProbe family is a set of flow-oriented applications, … Continue reading →
As we have released 2.4, it is now time to plan for the next release and highlight the list of features we plan to implement so we can start a discussion and get some feedback. The major changes we would … Continue reading →
The default ntopng configuration, is suitable for most of our users who deploy it on a home network or small enterprise network (typically a /24 network) with link speed <= 100 Mbit. This does NOT mean that ntopng cannot operate … Continue reading →
At ntop we are on a mission to develop enterprise-grade networking software, mostly open-source, and free of charge for no-profit/research organizations. Since our inception, we have been passionately and resiliently developing software to allow our users to monitor, protect, and preserve their … Continue reading →
Traditionally ntop has focused on passive traffic analysis. However we have realized that the traffic monitoring world has changed and looking at network flows is no longer enough: People want to enforce policies: if the network is hit by a security threat you need to … Continue reading →
This to announce the release of nProbe 7.4. We have worked hard in this version to improve it in several way by better integrating it with ntopng, improving network performance metrics computation, ability to export data to big-data systems, make … Continue reading →
Edit: MySQL tables engine has been migrated to MyISAM in ntopng 2.4 so this post only applies for versions <= 2.3. This is the first post that tries to give hints on how to tweak MySQL settings to better accomodate … Continue reading →
This is to announce the release of n2disk 2.6. In this release we have made many changes to the indexing system adding a new flow-based index that should improve packet retrieval as well pave the way to flow+packet+l7 inspection+index integration … Continue reading →
