The setup process is complex.
PS & Technical Manager at a tech services company with 11-50 employees
When you buy an XDR provider, they give you a complete holistic story around it, showing what has happened, which email somebody has clicked on, whether there have been any changes, and whether there is any network activity.

Senior Tech. Lead at WE

It offers the same features you would get from a vendor that charges 250,000 British pounds for a fraction of the price.
Head of Cybersecurity at SES Water
The following year, the cost of just licensing was similar to what was paid the previous year for a new appliance along with the implementation and licensing costs.
Network Administrator at a educational organization with 51-200 employees
Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern.
Managing Director
It's really expensive.
Systems Engineer at a tech services company with 11-50 employees
The pricing is higher for Mimecast, particularly for the Indian market, where it is considered expensive.
Senior Tech. Lead at WE
Regarding the price, I think that in terms of similar products, it is pretty much in the same line, so I think it's reasonable.

iboss was the best solution for us because, no matter what domain you were in, everything is under a single pane of glass, which is exactly what we wanted.
Managing Director
As organizations move away from legacy applications and data centers, the SASE architecture and ZTNA-based operations become essential.
If you have the complete Forcepoint solution, it can integrate with other Forcepoint products, such as DLP solution and email gateway.
PS & Technical Manager at a tech services company with 11-50 employees
A distinct advantage of Mimecast is its ability to block phishing and impostor attacks, which are significant threats currently.
Senior Tech. Lead at WE
One of the most useful features is the threat remediation module, which can be used to remove malicious emails that may have been delivered or manually remove them.

Cloud gateway has strengthened remote web security and now needs better Mac and ISP support
The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

Has faced usability challenges while managing integrated components
We are working with web gateway and full endpoint security. URL filter is a notable feature. While it is not specifically related to Forcepoint Secure Web Gateway alone, if you have the complete Forcepoint solution, it can integrate with other Forcepoint products, such as DLP solution and email gateway. The URL filter of Forcepoint Secure Web Gateway is good for web gateway. Clients and consumers do not prefer it because the interface is not good. When using FSM with DLP, web gateway, and email gateway, upgrades cannot be performed simultaneously since Forcepoint Secure Web Gateway might need an upgrade while email gateway does not, despite having the same manager controlling them. Forcepoint Secure Web Gateway works well with banking and small companies. Email gateway is less needed as everything is moving to the cloud.
Ravishankar KumarPatel - PeerSpot reviewer

Email defenses have reduced phishing risk and support strong compliance and user awareness
The improvement needed is not necessarily in the product itself, but rather around how other organizations have evolved. The DLP discussion is no longer limited to email; it has gone to border level with companies like Zscaler, Netskope, and Palo Alto giving the complete full-stack SASE setup. When somebody has a SASE setup, then Mimecast Advanced Email Security DLP might not even be needed at a point in time. Mimecast Advanced Email Security needs to improve in this area because they are only focusing on a particular set of problems which is on email and human risk, whereas companies that need a slightly bigger picture will look elsewhere. The second thing is when you buy an XDR provider, they give you a complete holistic story around it, showing what has happened, which email somebody has clicked on, whether there have been any changes, and whether there is any network activity. You get a holistic picture. When pushing Mimecast Advanced Email Security to end customers, people are more often saying that they would rather buy XDR from another provider because the story when an analyst sees is complete in terms of what they see, whereas they only get an email story from Mimecast Advanced Email Security. Mimecast Advanced Email Security has to improve there. Companies like Abnormal AI cover more on UEBA and user behavior, and there are many things for Mimecast Advanced Email Security to improve in this area as well. It is less of a technology issue; they are doing very well on email. The conversation for them to have is on how to get into a broader level or how to get a tie-up to become a broader supplier. At least from a service provider landscape, I can say that.
