It's a very useful tool to mitigate and protect your enterprise.
The network attacks reduced by approximately 60% after using that, even without customizing the custom configuration yet.
For a very little investment, I was able to increase the security of my network.
We had budgeted about thirty lakhs, but after negotiating with SonicWall NSa, we saved almost ten lakh rupees in a year.
The quick resolution of issues with Fortinet FortiGate is due to the support of the company and the fact that the equipment is easy to work with.
I would rate the technical support for Fortinet FortiGate a ten out of ten.
As a solution provider, when I encounter problems, I connect directly with Fortinet support, and they provide solutions within a very short time.
Compared to some open-source projects with weak support, OPNsense stands out for having both a strong community and commercial backing options.
I mainly rely on community support since the solution is open source.
If you say you do not have one, it is finished. This is where the monopoly starts.
SonicWall support is always available to help us on an immediate basis.
The support from SonicWall was excellent.
SonicWall support is very helpful and responsive.
They scale up really well from smaller models like the FortiGate 40 and 50 to bigger sites with the FortiGate 100 for more throughput - up to enterprise datacenters.
The variation comes in terms of the interfaces and throughputs, but from a security perspective, you get the same benefit, irrespective of whether you have an entry-level unit or an enterprise.
We determine sizing based on multiple factors: number of users, available links, traffic types, server count, services in use, and whether services will be published.
OPNsense is an extremely scalable solution.
I use Zenarmor, pinning it to one core for packet inspection, and the CPU performance seems very good.
OPNsense's scalability is excellent; I just need to resize my hardware and upgrade the server, and voilà, I am good to go.
I would rate its scalability around eight out of ten, meaning there are no issues, and it is pretty easy to scale.
Regarding scalability, it's important to ascertain the customer's future requirements, as firewalls need to be sized according to their expected scalability, such as moving from 500 users today to more in the coming years.
SonicWall NSa is very supportive and capable of handling everything from smaller organizations to big enterprise-level organizations on a model-wise or configuration-wise basis.
We're experiencing 99.999% availability consistently.
I would rate the stability of Fortinet FortiGate a ten out of ten.
Currently, we are experiencing a general outage of one of the main internet service providers of the Dominican Republic, and we have not been impacted in our operations because with SD-WAN, we have another internet service provider and we are working with the second WAN connection without any disruption.
For home and small network use, OPNsense is also reliable, providing enterprise-grade security at no cost.
OPNsense is the same, but it does have a way of installing the Realtek drivers, which gives you a lot more stability overall on the system.
The only challenge faced was its inadequacy to manage large voice traffic effectively, even with dedicated hardware.
Configuration changes have been made that have reduced that latency.
The stability of SonicWall NSA is quite good.
When considering Sophos XG, which we also use, the logging and reporting functionality is notably more efficient.
These sessions should be around five to ten minutes long, allowing users and partners to quickly grasp the information without disrupting their daily tasks.
The solution should be able to implement machine learning and analytics of all the logs for threat detection and protection.
I would like the APIs to be more mature and more developed and have more options to automate threat hunting.
Enhancing its performance for significant amounts of data traffic would make it closer to a perfect solution.
It would be beneficial if they could create some videos on how to set it up themselves.
More details in the analytical tools offered would be appreciated since it is not yet mature.
At those times, the CPU spikes considerably, and due to that, the firewall response becomes slow.
There are some aspects of the dashboard configuration or customization that could be improved.
Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us.
It offers cost savings as it is generally cheaper than the competition.
It is about 20% cheaper.
It is free.
They use AI for packet inspection, which integrates with OPNsense and pfSense.
I consider the pricing of OPNsense to be high when compared with other market products.
SonicWall is much cheaper compared to Fortinet, particularly regarding renewal and licensing costs.
I would rate the price of the product as seven out of ten.
These features help reduce our downtime, manage the ISPs, and deploy SLAs for all the website traffic.
The most valuable feature of FortiGate is FortiView which provides proactive monitoring.
We got a firewall and gave an SSL VPN to my client to connect to their servers, after which, such kind of activities involving ransomware attacks stopped.
The most valuable features include the basic firewall functionality and the GeoIP location services.
I can have a Wi-Fi VLAN and feel secure that the server network or the VM network that I have on a different VLAN are isolated, and they cannot talk to one another, which adds a great level of security.
It offers enterprise-grade features such as intrusion detection and prevention system, VPN support, traffic shaping, and web filtering, all without license cost.
Real-time deep memory inspection is very helpful and has had a positive impact on our security posture.
SonicWall NSA's most valuable features are its SD-WAN and a system RTBI that blocks all attacks.
We were the only organization that remained secure with a zero infection rate.

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.
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.
