Sentiment score
5.5
Organizations report a 150% ROI from Skyhigh Security, with users expressing satisfaction despite some lacking complete clarity.

Senior Consultant Proxy Engineering at a financial services firm with 10,001+ employees
I have seen some cost effectiveness from iboss; it has reduced certain support requirements, making it a more hands-off solution.
Managing Director
There is definitely a return on investment when using Mimecast, as it blocks phishing emails, reducing the risk of significant financial losses.

Educational Technology Coordinator at a performing arts with 201-500 employees
If Mimecast Email Security introduces API solutions, it will dominate the market.
Email Security Engineer at Logic Infosecurity
From what I've seen from the MSP, it seems quite complicated to manage the configuration itself.

We've experienced zero downtime.
Head of Cybersecurity at SES Water
Our biggest problem with their service was it did not recognize the device despite our ClearPass sending information to the iboss box.
Network Administrator at a educational organization with 51-200 employees
They confirm it's a good solution where only one or two rare emails get through, while the rest are properly blocked without any issues.
Email Security Engineer at Logic Infosecurity
The issues we did have were causing quite a lot of problems.
IT Manager at a logistics company with 201-500 employees
We did not face any downtime on that site, so it is quite reliable.

It has many gaps, so I think some customers take three months and up to six months for the deployment of Skyhigh Security.

Room For Improvement

Iboss struggles with Mac support, ISP integration in India, and needs improvements in security features and cloud integration.
Mimecast Advanced Email Security is criticized for complex installation, costly pricing, and numerous functionality and support issues.
Skyhigh Security's platform has performance, scalability, and integration issues, with a confusing interface and limited training resources.
It is not as intuitive as the rest of the platform.
Head of Cybersecurity at SES Water
We also had a problem with a transition when we upgraded from one appliance of theirs to another, but their engineer lost a good deal of our data.
Network Administrator at a educational organization with 51-200 employees
Our iboss subscription access should be more secure with an OTP or VPN etc.
A lot of emails were missed despite being known samples.
Senior Tech. Lead at WE

Skyhigh Security is quite simple, but if there is any improvement in the GUI, it will be quite easy for us because it looks a legacy interface.
Technical Associate Network Security at Valuepoint Systems
The solution has room for improvement in its DDoS protection.
Network Architect at a tech services company with 201-500 employees
The UI is another area where there is room for improvement in the product.

Setup Cost

Iboss offers competitive, transparent pricing with valuable cloud solutions, appealing to enterprises for predictable budgeting and desired functionality.
Enterprise buyers view Mimecast's email security as costly, with subscription fees per user and competitors like Microsoft Defender more affordable.
Skyhigh Security is pricier, suiting large enterprises, with discounts for multi-year or McAfee relationships, justifying costs with features.
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
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.
IT Manager at a logistics company with 201-500 employees
 

Valuable Features

Iboss provides comprehensive cloud security with advanced features, enhancing data protection and management efficiency for network security.
Mimecast Advanced Email Security provides comprehensive protection, easy integration, user-friendly setup, and valuable insights for enhanced email security.
Skyhigh Security offers comprehensive cloud protection with shadow IT detection, user analytics, strong encryption, and scalable deployment options.
The solution's mental health function can detect if someone needs help.
Head of Cybersecurity at SES Water
It's given us a lot more visibility into our computer assets that may be infected with viruses and also shows us people who have unusually large uploads or might be engaging in high-risk activities, such as searches or going to sites not categorized by their web crawler.
Educational Technology Coordinator at a performing arts with 201-500 employees
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
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.
Information Security Analyst at Enfield Central Library
Mimecast Email Security includes the best gateway solution across all Cisco, Trend Micro, and other solutions.
Email Security Engineer at Logic Infosecurity
The cloud security features are the most valuable.
Network Architect at a tech services company with 201-500 employees
It is actually very flexible, so I think that is the opportunity since it is not resource-intensive.
Secure at ESCARE COLtd
We operate in a major financial sector in India, and that is why we use Skyhigh Security to reroute all our traffic via proxy for our security.

Ashok Ananthula - PeerSpot reviewer

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.

Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Proxy integration has strengthened email security and centralized monitoring for all branches
We have nearly 900 plus branches here, where we have rerouted our traffic through proxy like Trellix Skyhigh Security. We operate in a major financial sector in India, and that is why we use Skyhigh Security to reroute all our traffic via proxy for our security. Only then will it reach our gateway. We monitor all the URLs and the plant IPs in our proxy. We are tracing those IPs to see whether they have a valid code or not. We also check with Trellix Sandbox to determine whether the URL is malicious or not. Additionally, we have included our Cisco Umbrella with our proxy, so the DNS resolution happens on our Umbrella side. We continuously monitor the traffic on our proxy side. The threat protection feature is a major useful thing because for our 900 branches we monitor with this proxy only. If any issue or any URL does not reach, it is quite helpful to check whether the issue is in the proxy side or in the actual end-user side. It is quite easy to monitor. We do not get all those things from the firewall end, and it is quite easy to gather that information from the proxy, which is a major benefit here. It also majorly helps to hide our actual IPs, as we have directed all the IPs from the proxy, making it very helpful to hide our internal servers.
