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

"The simplicity of the product is commendable."
"The technical support is top-notch."
"For the information security team, the security level was improved because it helped to manage and prevent rogue devices from connecting to the corporate network. The reporting was granular, and reports we scheduled for delivery on Portnox were useful during investigations and audits, especially in cases where the IP address changed."
"There is an add-on feature for application control to kill unwanted applications when launched on a user's device."
"It's agentless, and it's scalable."
"The product's initial setup phase was straightforward."
"Technical support was very helpful when we needed them."
"The ability of the product to search the entire network and know what you have hidden on your network."
"The solution offers very good visibility."
"Sophos Network Access Control has a useful interface, and I like its dashboard, which is very useful for us to check everything."
"I found all Sophos Network Access Control features valuable, but IP blocking is the most useful."
"What Sophos has done is integrate almost the entire OSI layer infrastructure. It gives me visibility across my infrastructure. It gives me visibility into all the mobile devices that are on my network and into the security I have on those mobile devices."
"There is really good visibility for the appliance."
"I am very satisfied with this solution overall. All of the features that we use have been working successfully."
"Sophos Network Access Control has many valuable features: for access controls, MAC binding is available, the authentication page is useful, and continuous device assessments have a positive impact on our network security management."
"The most valuable features of Sophos Network Access Control are the quick response times to threats and reliable security."
 

Cons

"We have seen instances where the older version stops working properly, and we have to update each system individually."
"The integration between Portnox CORE and Portnox CLEAR can be better. These are two different systems, and there is no unique console for both devices. Portnox CORE is agentless, whereas Portnox CLEAR is not agentless."
"Portnox CORE can improve on support for unmanaged switches (or hubs) and other brands of network devices. These kinds of devices are still in use in organisations, especially SMEs who cannot afford to buy a managed switch."
"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."
"Their filtering system tends to lag quite a bit, so when I'm doing filtering at times, it doesn't filter the items properly."
"The solution did have some stability issues, however, all I had to do was restart it."
"Allowing for a search of MAC addresses in the interface, whether they are authenticated on the network or not, would be beneficial. Currently, it only finds authenticated MAC addresses, which complicates troubleshooting when the same MAC address is used for different requests."
"The price could be better."
"The difficult thing was finding the metrics."
"Sophos Network Access Control needs improvement regarding its slow interface, loading time, and reporting."
"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."
"An area that could be improved is the information about licensing, which is fairly confusing at present."
"Endpoint and firewall synchronization is not as smooth as we are expecting from Sophos Network Access Control."
"I'd like to see them include direct integration with Active Directory."
"In order to provide better management, it would be ideal with they offered better plugins for their firewall."
"Sometimes we encounter intermediate-level support staff who use trial-and-error approaches, but sometimes we receive support from excellent staff members who resolve issues within seconds."
 

Pricing and Cost Advice

"The pricing is a bit high, possibly due to the cloud features and running instances across regions like the US, Asia, and Europe."
"The vendor price is fair."
"The users are not very happy with the new licensing option where there is only a subscription license. There is no perpetual license."
"Portnox CORE's pricing is adequate and cheaper compared to other complex solutions. Its licensing costs are yearly and include support. Cost is calculated per device."
"The solution is very expensive and I would rate it 10 out of 10."
"The cost of Portnox Clear is reasonable."
"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."
"It is not bad. It is a bit on the high side, but considering the cloud features and how much it costs to run the instance in the cloud, it is not unreasonable. We do have RADIUS servers for the US, Asia, and Europe."
"Sophos Network Access Control is very cheap compared to other solutions like Cisco, Barracuda, and Palo Alto."
"Sophos Network Access Control is an expensive solution."
"It is quite expensive."
"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."
"I rate the price of Sophos Network Access Control a five out of ten."
"It provides a moderate pricing option for all of its features and benefits."
