Why do I need network visibility?
Unless you set up a visibility solution, you do not know what is happening in your network. How will you be able to efficiently maintain your network without visibility? Do not let your IT engineers drive blind.
Why is network visibility cost-effective?
Take a moment to estimate the cost to your organization of every hour of downtime, or these random 10-minute periods where the network is slow and nodoby knows why. What if you could cut downtime in half by easily spotting bandwidth hogs, disconnecting infected hosts, or proactively dealing with incidents, anomalies or attacks?
What is Network Polygraph?
Network Polygraph is a software-as-a-service (SaaS) visibility solution.
A more technical description: Network Polygraph is a cloud-based, offsite, SaaS NetFlow analysis service.
What is NetFlow?
Routers can export statistics on the data packets they observe, using a protocol called NetFlow. Essentially, these are small per-connection summaries: involved IP addresses, number of bytes exchanged, etcetera.
Polygraph collects these stats and offers you great visibility over what happens in your network.
What if I do not have NetFlow?
While NetFlow is a de facto industry standard, some vendors implement alternative solutions that we also support, including sFlow, J-Flow and IPFIX. Additionally, some lower-end routers support none of these. In this case, Ask us how to get NetFlow support very cheaply.
Why is offsite, SaaS NetFlow-based visibility solution more convenient?
Alternative solutions require licensing either software or hardware that must be deployed in your premises. They have steep up-front costs with uncertain returns, and entail hidden deployment and maintenance costs. In contrast, our NetFlow-based solution entails no up-front costs, is hosted offsite for maximal convenience, and lets you re-evaluate your choice later (and even switch to another solution if you want).
If offsite network monitoring is not a good choice for you, though, we still have on-premises deployment with our Enterprise edition.
What about security. Will my traffic travel unencrypted over the Internet?
No, your network traffic will not travel over the Internet through our servers. NetFlow never exports the actual data carried over your network, but only small summaries of each connection, such as IP addresses and the total amount of data exchanged.
We set up encrypted tunnels and all communications are protected with SSL.
(On-premises deployment with our Enterprise edition is always an option.)
What sort of visibility will I get?
You will get the best insights on the traffic, powered by our proprietary NetFlow-based traffic classification and anomaly detection engines. Check the screenshots or request access to a demo deployment with real, anonymized traffic to see for yourself.
What is unique about Network Polygraph?
Our service incorporates a series of proprietary algorithms that offer increased visibility compared to other NetFlow-based solutions. Our technology includes state-of-art machine learning algorithms that aid in L7 application identification attack detection.
A distinct feature of Polygraph is that it pairs depth of analysis with an agile and responsive user interface.
What is the overhead of NetFlow on the network?
NetFlow will typically introduce 0.5% extra bandwidth usage. This is a tiny price to pay for understanding what happens in the 99.5% remaining capacity.
Does Network Polygraph support my router/switch/firewall?
Almost surely, yes: we support devices from all major vendors, as well as open-source NetFlow generators. Check whether your device models support NetFlow, sFlow, IPFIX or jFlow. If still unsure, contact us for assistance at email@example.com.
I am unsure how to configure my devices. Will you help?
Where needed, we will help you or your engineer configure your hardware. Again, contact us at firstname.lastname@example.org.
Can I schedule a guided demo with you?
Please contact us at email@example.com. One of our engineers will contact you to schedule a session with you.
I have a question not covered in this short FAQ. What do I do?
