What information is sent to the Sinefa cloud?
Sinefa does not sent your actual network data to the cloud. Instead, Sinefa probes (physical, virtual, and/or cloud) process your network data packets using Layer 7 Deep Packet Inspection. That data is then classified using our 10,000+ app and app group signatures and converted to metadata. The metadata is then deduplicated, compressed and then encrypted before being sent to the Sinefa cloud.
Is my metadata encrypted?
Yes, both in flight and at rest. Metadata is encrypted when sent to the Sinefa cloud and is also encrypted when stored in Sinefa's cloud database. A dedicated database is created for each account.
How much bandwidth does the Sinefa probe use to send metadata into the cloud?
The metadata sent from the probe to the Sinefa cloud has a low traffic footprint which equates to up to 0.4% of the traffic being inspected. For example, if there is 100Mbps of usage on the link up to 400kbps of bandwidth may be used for metadata transport to the Sinefa cloud.
Can my traffic visibility metadata be lost?
No, that is one of the beautiful things about our cloud-based soultion. No data is stored on our Probes. All metadata is stored in the Sinefa cloud. Sinefa has an ever increasing number of cloud regions around the world. Metadata is stored and backed up across these regions.
How does Sinefa classify HTTPS traffic?
Sinefa can classify a number of encrypted applications. When it comes to HTTPS, Sinefa displays the Certificate Common Name instead of the URL/Website. So under Reports | Websites, any object with "*." is a HTTPS session. Popular HTTPS apps like YouTube, Instagram, Google apps etc are classified as there respective Applications ... not as HTTPS.
Does Sinefa have hardware probes available?
Yes. Hardware probes are zero config and simply require a DHCP address (by default) and access to the internet via HTTPS/SSL to get started. Additional network settings for the probes can be configured to suit the network environment. See Networking Fundamentals for more info.
What happens to my network if the hardware probe fails?
In the unlikely event that your physical probe should fail or if you experience a loss of power to the probe, the probe will fail to wire ensuring that your network is not effected. This "bypass" function is achieved using bypass bridges on the probes. These bridges can be copper or fiber interfaces. Visibility and shaping functionality will be suspended until the probe is replaced or power is restored.
Can the virtual probe be deployed in-line and perform shaping?
Yes. An in-line Virtual deployment is typically referred to as "service chaining" as it gets chained alongside other functions like router, firewall, SD-WAN etc. See how to standup a Sinefa probe on VMware or click here for a simple service chain example.
Where is my data hosted? Are you hosted in my country/region/location?
Sinefa has a number of cloud regions across the US, Australia, South East Asia and Europe. Accounts are automatically created as close as possible to where you are located.
Can I access Sinefa visibility data on my mobile device/smartphone?
Yes. We have a mobile app to help you visualise Live traffic on your network wherever you are. The Sinefa app is available of iOS and Android. Note: this app does not monitor the traffic on your smartphone.
When should I see data in the Sinefa cloud?
The fist step is to deploy a Sinefa probe in your network. You then have to register the probe to your account and subscribe it. Hardware probes can be registered using their serial numbers. Once the probe is subscribed and can see traffic, you will start to see data in the Sinefa cloud.
