Unified access control has improved compliance visibility and simplified passwordless access
There is work to be done when it comes to making the solution more seamless. For example, when a user is denied access, they would need a way to maybe self-resolve themselves, perhaps a way to generate a ticket on their own, something around resolutions. When it comes to users using the product, that is where good products are differentiated from products that are a bit of a challenge. Portnox has much to do in terms of their reporting. The generated reports need improvement. Things that other tools would say are normal are usually not present. For example, there is a page called NAS devices or NAS network that is able to show the switches that have been managed. Currently, there is no way of generating an easy report or an easy way of just generating something to tell the customer what they have been able to achieve so far. This is not done yet and is still very manual. I think there is work to be done there. More integrations around the various products being used would be beneficial. So far I have not encountered any major challenge. Where there was a challenge, I think support came in and helped us resolve. In fact, most of the challenges are not with the product; they are with the customer environment. I think that is just to update their documentation where they have come across a new vendor for easier integrations in the future.

Have faced delays in support despite strong multi-layer policy configuration
I have observed some disadvantages as we have experienced one particular problem. We were facing an issue of synchronization of the endpoint with our firewall with help on a cloud for heartbeat syncing. However, it was not syncing as per our requirement. The user has to connect our firewall with the help of VPN. We were supposed to assume a solution on a cloud, which has good synchronization on a cloud with Sophos Central. It will sync with our firewall as well with the help of Sophos Central. Endpoint and firewall synchronization is not as smooth as we are expecting from Sophos Network Access Control. We have to connect with VPN. We are expecting that if we have already installed an endpoint on our system and it is connected to the internet, then it must be synchronized on a cloud with Sophos Central. Through Sophos Central, it must connect with our firewall. If the endpoint is configured on Sophos Central and the firewall is also configured in Sophos Central, then there should be no need to connect to VPN.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"One of the features I enjoyed the most about Portnox was the ability to dive in with proper details on an endpoint."
"Portnox positively impacts our organization by providing us massive peace of mind and drastically cutting down our operational overhead."
"The most important feature is that this solution is agentless. So, you don't have to install any agents on endpoints."
"Most customers feel value immediately upon deployment; they are able to see what is connected and apply the policies."
"The solution has a valuable reporting feature."
"Portnox is a highly effective tool that will significantly lower your incident resolution times, so be prepared to push through a slight learning curve at the beginning."
"Portnox is better than other solutions that I tried before, at least with Cisco, because it has lots of features that are not included in Cisco, so it is the best for me."
"Portnox's pricing is very conservative and offers great value for money."
"I am very satisfied with this solution overall. All of the features that we use have been working successfully."
"Sophos' technical support is great, very fast and responsive, and they always know how to fix the problem."
"Sophos has helped us to save time and money and to better manage web activities. It has also helped us to reduce misuse of the network and restrict hacking attempts."
"The solution offers very good visibility."
"Sophos Network Access Control saves our clients time and money."
"The biggest advantage of Sophos Network Access Control is that it is very synchronized with the security on both the endpoint and the firewall on a single platform, and it is easy to maintain."
"What Sophos has done is integrate almost the entire OSI layer infrastructure; it gives me visibility across my infrastructure, into all the mobile devices that are on my network and the security I have on those mobile devices, my users, my servers, what is happening at all my gateways, and visibility on my switches, so it gives me a global view of my infrastructure."
"The return on our investment was huge, mostly due to the time saved in managing thousands of physical endpoints."
 

Cons

"However, problems arise when the same MAC address is requested for a different project. Our current system only finds authenticated MAC addresses, making it difficult to troubleshoot when the same device is used for multiple purposes."
"While Portnox is solid, there is definitely room for improvement, particularly with the user interface."
"Portnox has some difficulties with stability; sometimes there are glitches, and settings are not clear."
"I think while Portnox provides wonderful technology, the support and maintenance agreements are problematic."
"One area for improvement would be deeper reporting and analytics capabilities for Portnox, particularly for long-term trend analysis and compliance reporting."
"During my daily use, I noticed that if you have many devices being managed by a particular server, any device being managed by that server takes quite a bit of time to respond."
"There is room for improvement regarding Portnox's pricing strategies."
"The product should consider more integration with vendors like Huawei. It should also improve visibility. The solution should offer a partner portal that can provide customers training on the in and out of the solution."
"Users are not controlled by role-based access; it's basically device-based control. The definition of role-based control is a little vague here because on the cloud level, it regulates access rather than tasks."
"The solution can improve the for applying policies. They can be complex depending don't the group they are applied to."
"It would be good if Sophos Network Access Control had better integration with other devices."
"There is room for improvement in pricing."
"In order to provide better management, it would be ideal with they offered better plugins for their firewall."
"What needs to be improved on is the fact that Sophos consumes a lot of processor resources and, once it starts scanning, the RAM utilization is very high."
"I would like to be able to fully customize the reports."
"Sophos Network Access Control could be improved by having an ASIC chip similar to FortiNAC, as this would provide better processing for big organizations."
 

Pricing and Cost Advice

"Pricing is quite reasonable."
"The vendor price is fair."
"The licensing module should be reviewed to count the number of devices instead of port numbers of total switches. There is a case for this where not all ports for a switch are used by devices. Unused ports are calculated in the license, then the customer pays for license for those unused ports."
"The users are not very happy with the new licensing option where there is only a subscription license. There is no perpetual license."
"The cost of Portnox Clear is reasonable."
"The tool is more expensive than Fortinet."
"We pay for port licensing and support on a yearly basis, and it's not cheap."
"The pricing is a bit high, possibly due to the cloud features and running instances across regions like the US, Asia, and Europe."
"It provides a moderate pricing option for all of its features and benefits."
"Sophos Network Access Control is very cheap compared to other solutions like Cisco, Barracuda, and Palo Alto."
"Sophos Network Access Control is costly but has a similar price range as CrowdStrike and Check Point. The product can get more market share if Sophos can play around with Sophos Network Access Control pricing and improve it."
"It is quite expensive."
"I rate the price of Sophos Network Access Control a five out of ten."
"Sophos Network Access Control is an expensive solution."
