Achieving Seamless Email Security and Encryption while Managing Temporary Email Storage Limits
We continue to use Sophos products and remain with the company. For firewall protection, we use XGS systems. We have provided Sophos Email Gateway for one of our clients. We have integrated Sophos Email with our internal email server, using it for both outbound and inbound traffic. Integration with Office 365 protection for Sophos Email Security works smoothly without any challenges. The solution is totally cloud-based. I recommend Sophos Email for mid-sized companies as it is a good option, though it may not be ideal for large-scale or small businesses. I have not tried incorporating AI technology with Sophos Email yet. I am Bhanu Prakash, Technical Head for Systek Services, and can be reached at b.hanu@teamsistek.com. I am a partner with Sophos. Overall rating for Sophos Email: 10/10.

Quotes from Members

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

Pros

"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"The most valuable feature is the straightforward setup."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"The speed and stability were fine."
"Sophos Email is a stable solution."
"The filtering capabilities are precious and far superior to others I've used. It's intuitive in what it pushes to quarantine, and users can quickly review, free, or delete items without needing an administrator, making it ideal for a multi-user environment."
"Sophos Email offers encryption and malware protection, provides visibility into emails, has 99% accuracy in catching spam, enhances organizational safety, integrates with various vendors like Microsoft, is deployable with any email service, prevents data loss, features authentication rules, synchronizes with Active Directory and Azure, and includes a self-service portal. The product is very flexible."
"Sophos Email provides both inbound and outbound filtering."
"The most valuable feature is its email security."
"The best thing about it is the logs."
"Sophos Email is in the cloud and integrated with its firewall."

Cons

"I rated the overall solution a five out of ten. If a user is looking for a low-budget solution with mid-level security without AI features, Kaspersky Security for Mail Server is suitable."
"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"The solution is not 100 percent stable and that can use improvement."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"Servicing and support are areas with shortcomings where the solution needs to improve."
"Lacks visibility into spam emails."
"The tool's integration becomes an issue when the internet connection is weak."
"However, the setup was tricky, particularly with the DNS routing between Microsoft Exchange Online and Sophos cloud services. It took me about four attempts to get it working correctly. Despite that, Sophos Email does everything we need, so we don't require any additional capabilities now."
"Enhancing rule creation and customization features would provide users with greater control over their email security settings."
"Sophos Email needs to increase the number of promos."
"The tool’s stability should be improved."
"Sophos Email could better detect fake emails, especially when the domain names are similar. It needs to improve spotting spoofed domains, like when one letter differs in a domain name. It also needs to incorporate AI detection. Barracuda detects suspicious emails better. However, malware scanning is better in Sophos Email."
More Sophos Email cons
 

Pricing and Cost Advice

"The solution offers one of the best prices possible to its users, making it even better than Barracuda. Kaspersky Security for Mail Server is ten times cheaper than Barracuda."
"The solution is not expensive."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"My company makes annual payments towards the licensing costs solution."
"The pricing could improve by having additional discounts. For example, when customers buy have more than 50 or more users, there should be additional discounts."
"The platform is inexpensive. It offers a cost-effective licensing model. We purchase its yearly license."
"I would rate the pricing of Sophos Email as a six. It is considered affordable as a standalone product, and there are no additional costs besides licensing. The pricing is fixed."

"The pricing is quite reasonable, with a fixed cost and no additional charges."
