What is SonicWall NSa?

SonicWall NSa dispenses advanced threat protection using a high-performance security platform. The NSa series implements intuitive deep learning technologies in the SonicWall Capture Cloud Platform to dispatch the automated real-time threat detection and deterrence enterprise organizations need today. SonicWall Network Security appliance (NSa) series is best for mid-sized organizations to distributed enterprises and data centers.

SonicWall NSa series next-generation firewalls (NFGWS) combine two very robust security ideologies to deliver advanced threat protection to keep users’ networks safe. Boosting SonicWall’s multi-engine advanced threat protection (ATP) is their Real-time Deep Memory Inspection (RTDMI™). The RTDMI intuitively identifies and stops aggressive zero-day threats and vicious malware by investigating memory directly. This real-time process allows SonicWall RTDMI to be accurate, lessen false positives and discover and alleviate malicious threats and attacks. SonicWall’s single-pass Reassembly-Free Deep Packet Inspection (RFDPI) will audit every byte of each and every packet by investigating both outbound and inbound traffic on the firewall. By combining the SonicWall Capture Cloud Platform along with on-box offerings such as intrusion prevention, web/URL filtering, and anti-malware, the NSa series is able to block the most malicious and dangerous threats at the gateway.

Senior Manager INFOSEC AND Risk ASSESSMENT Engineering at Atlas Systems

The centralized console is great for managing multiple branches. It's a very simple console to connect all three of our branches in the US and India. We connect through three firewalls in a single console and manage any policy. So, if we need to change a policy, the global admin can connect from anywhere and easily make changes. Log usage is also very easy. The threat prevention capabilities are very good. Preventing the latest threats is very easy. You can define rules, and it automatically alerts you. For example, if there's a sudden increase in malicious spam, it will notify you immediately.

An area for improvement in SonicWall NSa is that sometimes, we experience bugs when upgrading, so we have to contact their technical support to fix issues. It would be much easier if this improvement was in place: if the one-time password which is built-in, was provided as an OTP for the administrator logging into the console, so that we'll have a quicker awareness of it, rather than needing to check emails for it. Having a Telegram or WhatsApp bot integrated with the device, for example, will be very helpful for us, so we can instantly take action, without us needing to log into and check our emails, meaning we'll be able to put things right faster. This may not be possible in SonicWall NSa, but I'm also looking for any kind of controller or device for the Windows server or client, e.g. Windows 11 and Windows 10 from SonicWall NSa itself, so that a security domain or the gateway of the organization would be able to identify the latest update for a product, whether that product is installed or not. This feature would be very helpful, and it's what I'd like to see in the next release.

Additionally, SonicWall firewalls supply absolute protection by executing complete inspection and decryption of SSH and TLS/SSL encryption connections - no matter the port or protocol. The firewall takes a deep dive into each and every packet (the header and data) routing out any anomalies, zero-day intrusions, threats, and protocol non-compliance. Users can also define unique criteria specific to their organization to ensure their networks remain safe. This aggressive deep packet inspection is able to identify and block malicious attacks, stop dangerous malware downloads, prevent the spread of infections, and defeat command and control (C&C) communications and data exfiltration. Protocols involving inclusion and exclusion allow users complete control to decide, based on specific governance policies, organizational policies, or government or legal compliance, which traffic is to be investigated for decryption or inspection.

SonicWall Nsa offers enterprise organizations the network control and fluid flexibility they desire using an intrusion prevention system (IPS), VPN, real-time visualization, and other advanced powerful security features, making it a popular firewall solution in today's marketplace.
