IT Officer at MVA Fund
The IT department has saved time and cost, as they do not have to run up and down fighting with malicious spam or malicious attacks.
Business Development Manager at Procter & Gamble
We do not require monitoring multiple portals, so it is a one-place solution.
Senior Technician at a tech vendor with 501-1,000 employees
Importantly, we didn’t need to hire any additional staff; we were able to absorb this responsibility using our existing team.
Manager Security Operations Center at a educational organization with 10,001+ employees
I estimate that we have improved our efficiency, especially for phishing campaigns where we can handle multiple similar emails together, which has reduced repetitive analyst work and improved our response time.
Soc Analyst at a manufacturing company with 10,001+ employees
I think the ROI for us is primarily in reduced security risk and reduced analyst time.

Barracuda does not limit you based on how many mailboxes or users you have, which is one of the good things for Barracuda.
Director Of Technology at PT Exa Teknologi Indonesia
Barracuda Email Protection's scalability is very good because it handles all my clients' emails and all my organization emails.
Business Development Manager at Procter & Gamble
Scalability is expensive for Barracuda Email Protection.
IT Officer at MVA Fund
Despite nearly doubling the number of mailboxes and adding significantly more detection rules, the service remains just as fast as it was when we first implemented it.
Manager Security Operations Center at a educational organization with 10,001+ employees
Its scalability is also good, as it can scale with the number of protected mailboxes or users, or as email volume grows, supporting enterprise development across Microsoft 365 or Google Workspace.
Soc Analyst at a manufacturing company with 10,001+ employees
We have a fairly large Microsoft 365 environment and haven't had any problems with the platform keeping up with our email volume.

8.7
Sublime Security offers stable, reliable email security with quick performance, efficient threat detection, and no downtime or crashes.
Customers chose a different product after experiencing a problem when they upgraded the firmware, which caused the system to restart multiple times during working hours.

Barracuda Email Protection's stability is good, with no lagging, no crashes, and no errors.
Cybersecurity Team Leader at EMAK For Computer Manufacturing (ECM)
I think Barracuda Email Protection is stable and very reliable.

Sublime Security acted quickly; once Microsoft alerted Outlook about the incoming email, Sublime Security managed to pull it from the stream before it had a chance to appear in the user's inbox.
Manager Security Operations Center at a educational organization with 10,001+ employees
 

Room For Improvement

Barracuda Email Protection needs AI, zero trust, user-friendly setup, enhanced reporting, and pricing adjustments for small businesses.
Sublime Security should enhance user onboarding, integration, customization, and reporting while addressing pricing and reducing false positives.
The day we stop improving is the day we die.
Group ICT Manager at a mining and metals company with 501-1,000 employees
Users must go through an induction session where I guide them in configuring quarantine alerts rather than having default settings based on group membership.
Director, Information Technology at St Albans High School For Girls
Barracuda Email Protection could improve in the future to make it more competitive by addressing the fact that Barracuda started with anti-spam and email protection, but now they are moving more to cloud-based solutions rather than device-based or hardware-based solutions.
Director Of Technology at PT Exa Teknologi Indonesia
Often I have to prepare reports for our CEOs, and they want it in a less technical way, a simpler view of things such as threats blocked, incidents investigated, and overall risk reduction.
Technical Lead at a consultancy with 11-50 employees
While they do provide API-level access and web hooks, I believe more out-of-the-box integrations with SOAR platforms and SIEM tools would enhance Sublime's value.
Manager Security Operations Center at a educational organization with 10,001+ employees
One breach could potentially put a small company out of business, so having a tool such as this might save them from that fate.
Partner Account Manager at a wholesaler/distributor with 51-200 employees
 

Setup Cost

Barracuda Email Protection's pricing ranges from affordable to expensive, with better deals potentially available through negotiation.
Sublime Security's pricing is higher but justified by effective threat prevention, with competitive AWS Marketplace setup and licensing.
I find that Barracuda Email Protection has a very good licensing model, providing capable features at a very good and affordable price.
Cybersecurity Team Leader at EMAK For Computer Manufacturing (ECM)
In my experience, the pricing, setup cost, and licensing for Barracuda Email Protection are competitively priced, making it very affordable for any size of organization.

I would say the price for Barracuda Email Protection is very nice; the solution is not expensive.

I can also understand why some people might say it's expensive.

It's competitive with its peers, especially for the number of mailboxes we have.

Xavie Simons - PeerSpot reviewer
Business Development Manager at Procter & Gamble
Improved email security has reduced spam, simplified encrypted mail, and strengthened user trust
The best features Barracuda Email Protection offers include good spam filtering and very good sandboxing of all links, as well as good encryption. It also has integrated logging for user management of their own spam. It has better filtering technology, so few are false positives as well, with excellent anti-spam engines and logging. It is extremely easy to install, configure, and set up, and there is excellent message tracking for folks that say they have not received an email they were expecting. Integrated logging and user management make my daily work easier because it is very easy to log in and to manage this tool, hence making it a very good tool for email protection. It also has excellent, easy-to-add designated users as site administrators, and it is competitively priced. It has a user-friendly portal, strong cloud-based features, and no additional maintenance cost, along with responsive support. Barracuda Email Protection has positively impacted my organization by handling encryption better than any other tool I have used before, which has increased our email protection significantly. Our security has also increased from forty percent to sixty-five percent, especially when dealing with all the threats that come through emails. It has been a great tool because we can handle email delays and delays on file scanning. When our partners are happy, we are very happy, and it has helped us have less time chasing bad emails. The fast implementation of encrypted mail keeps employees working with less interruption since they are happy, satisfied, and secure.

Email defenses have reduced manual phishing work and now give clear visibility into threats
I'd say the best features Sublime Security offers are the threat detection and investigation capabilities, which are probably the most valuable part for us. I particularly appreciate the visibility into the email activity and the ability to investigate suspicious messages and understand why something was flagged. I'd say the protection against more sophisticated phishing and business email compromise attacks is also important. Those are difficult to deal with because they don't always contain obvious malware. The investigation capabilities of Sublime Security stand out because they surface themselves in a very nice, obvious way. So when we are investigating, they're just easy to spot and easy to identify. The UI is very clear for us, and overall it's just what we would expect. Regarding Sublime Security's AI capabilities, I think it's honestly pretty good. I haven't had any issues with either the governance side or the security side. I think Sublime Security has been very accurate. For us, it's certainly stopped a lot of the manual investigation that we often do for phishing emails or malicious emails. Occasionally, it does give us false positives, but that's just a five-minute review of something, so it still cuts a lot of time down.
