Barracuda Impersonation Protection uses Barracuda AI that leverages the metadata from internal, external, and historical emails to create an identity graph for each Microsoft 365 user. The identity graph uses email addresses, document types, names used, natural language analysis (NLP), and other data that define the unique communication patterns of an individual. These learned patterns allow Barracuda to identify behavioral, content, and link-forwarding anomalies in your company email communications. This real time protection secures your inbox from spear phishing, business email compromise, lateral phishing, and other targeted threats.

This listing offers a single pricing dimension. You pay per user for Impersonation Protection, part of the Email Protection product line. Pricing scales directly with your user count, so cost rises or falls as you add or remove users. You buy through a contract commitment rather than by usage. There are no separate tiers or instance sizes to choose from. To set your total, multiply the per-user rate by the number of users you need to protect.
Top-of-mind questions for buyers
What counts as one user for billing under Impersonation Protection?
You are billed per user, meaning each mailbox or person you enroll for protection. Your total equals the per-user rate times the number of users you protect. Adding or removing users changes your count directly. There is no separate charge based on email volume or data.
How is this contract billed compared to a usage-based option?
This listing uses a contract commitment. You commit upfront for a set number of users rather than paying based on live usage. Charges do not fluctuate with email traffic or activity. This structure suits organizations with a stable, known user count they want to protect continuously.
What email threats does Impersonation Protection focus on?
Impersonation Protection targets phishing, business email compromise, and spoofing attacks that impersonate people or brands. It analyzes communication patterns to flag anomalies and social-engineering attempts. This is one part of the broader Email Protection product line, so it centers on identity-based impersonation rather than every email security feature.

Email protection has reduced spam threats and now saves time through centralized control
Reviewed on Oct 15, 2026
Review provided by PeerSpot
What is our primary use case?
My main use case for Barracuda Email Protection is to ensure all emails are being securely delivered and we are receiving all secured email while preventing spam emails from reaching the inbox. I use it primarily as an email security solution.
A specific example of how Barracuda Email Protection helped my organization with email security is during vacation times such as Christmas, when many spam emails containing Amazon gift cards and vouchers arrive. Barracuda Email Protection has consistently prevented those emails from reaching end users and protected my client from these threats. That is one of the best examples I can provide.
Barracuda Email Protection has proven valuable for many capabilities, including the option to block domains. I can rate emails based on whether they have SPF value records, and I can determine if DMARC records are not in place. I receive all that information from senders, and Barracuda Email Protection protects against all those things. That is what I appreciate about the solution.
How has it helped my organization?
Barracuda Email Protection has positively impacted my organization by protecting my clients from spam emails and cyber attacks. That is the most helpful aspect, which has been beneficial for my organization's growth.
I have measured this impact by noticing that on a daily basis, approximately ten percent of emails are spam and contain threats or hacker techniques sent via email. All those threats have decreased, and it is having a positive impact on my organization's level.
What is most valuable?
The best features Barracuda Email Protection offers include the ability to block emails geolocation-wise, block domains, and block emails category-wise, such as drug-related emails, spam emails containing vouchers, and adult emails. All those things have been filtered out, and those features are very helpful.
I find myself using all features, not just one specific feature, because all those capabilities help me secure my email. I would say all the features are helpful rather than specifying one.
What needs improvement?
I would suggest improving Barracuda Email Protection by implementing AI modules into it. In the era of artificial intelligence, multiple AI scams are happening. Integrating AI modules could be an improvement plan, especially with dark emails emerging.
So far, everything is good in terms of user interface and support.
For how long have I used the solution?
I have been using Barracuda Email Protection for more than three years.
What do I think about the stability of the solution?
Barracuda Email Protection is stable.
What do I think about the scalability of the solution?
Barracuda Email Protection's scalability is good and growing well.
How are customer service and support?
The customer support for Barracuda Email Protection is better. I would rate the customer support an eight on a scale of one to ten.
Which solution did I use previously and why did I switch?
We have used multiple email protection solutions from different companies before Barracuda Email Protection. I preferred Barracuda because we have other products and solutions through Barracuda, Datto, and other offerings. That is the main reason why we switched to Barracuda Email Protection.
What was our ROI?
I have seen a return on investment by saving employee time. We do not require monitoring multiple portals, so it is a one-place solution.
What's my experience with pricing, setup cost, and licensing?
My experience with pricing, setup cost, and licensing for Barracuda Email Protection is that it is a bit high. However, when I look at the service and the features, I am satisfied with it.
Which other solutions did I evaluate?
Before choosing Barracuda Email Protection, we evaluated other options, but I do not remember those names as it has been a year or two. However, I felt Barracuda Email Protection was a better option.
What other advice do I have?
Governance and security regarding Barracuda Email Protection are good, and it covers everything in accordance with government rules and regulations. In terms of security, it is solid. That is a positive aspect.
Barracuda Email Protection is accurate and reliable, and I have seen good outputs from it.
Barracuda Email Protection is deployed in my organization on a public cloud. We are mostly deploying it for Microsoft 365 users and premium users. We do not use hybrid or on-premise solutions because everything is on cloud nowadays.
I would definitely recommend everyone to switch to Barracuda Email Protection and try the demo version first to see how things work. It has been helpful for our organization, and it can be beneficial if you work with it and test it. I rate Barracuda Email Protection a nine out of ten because it covers everything required for my needs, and I left one point for the improvement plans I have recommended.

Email monitoring has boosted phishing detection and simplifies rapid incident response
Reviewed on May 19, 2026
Review from a verified AWS customer
What is our primary use case?
Barracuda Email Protection is deployed on one of my clients, serving as the main email web gateway to deliver and receive emails. It has been set up as a DNS record method and is used to scan for potentially spam or phishing emails and harmful emails to block them. It is also used to protect unauthorized disclosure of data from my clients to the outside world.
What is most valuable?
The best features Barracuda Email Protection offers are its Advanced Threat Protection and Incident Response feature. As a SOC analyst or an incident responder, I am fond of the capability of the real-time monitoring and forensics of Barracuda Email Protection. I can quickly see what the content of the email is and receive alerts if any potential phishing emails or spam emails are detected as I want. I can also identify who interacted with those suspicious emails to limit any incidents that may occur. The bulk remediation feature is something that I am satisfied with.
With Advanced Threat Protection, what I appreciate is the real-time scanning of attachments and the real-time spam protection system.
Barracuda Email Protection has positively impacted my client's organization by reducing almost 50 to 60 percent of phishing emails, making it more secure and allowing us to feel safe from phishing incidents. Overall, the spam protection is also working great and has reduced a large number of spam emails being received by the organization. The phishing protection also works exceptionally well.
What needs improvement?
I wish the interface of Barracuda Email Protection could have worked in a more responsive way, as sometimes I feel it is slow or laggy when I try to interact with it.
For how long have I used the solution?
I have been using Barracuda Email Protection for around the last one year.
What do I think about the stability of the solution?
Barracuda Email Protection is quite stable in my experience.
What do I think about the scalability of the solution?
Barracuda Email Protection has handled increases in users or email volume very well.
How are customer service and support?
I have not reached out to Barracuda Email Protection's customer support directly, but my colleagues have, and they say it was a very good or very pleasant experience.
Which solution did I use previously and why did I switch?
I did not use any solution before Barracuda Email Protection; I was using the basic security provided by Outlook in Exchange only.
What was our ROI?
I am not sure about the financial part, as I was not the one who deployed or participated in licensing discussions. However, preventing incidents or seeing a reduction in the volume of incidents is something that reflects a good return on investment.
What's my experience with pricing, setup cost, and licensing?
I do not have insights regarding pricing, setup cost, or licensing, as I was not part of those discussions.
Which other solutions did I evaluate?
I did not evaluate any other options before choosing Barracuda Email Protection.
What other advice do I have?
To measure that 50 to 60 percent reduction, there was no baseline created, but that is a behavior I observed on Barracuda Email Protection's dashboard and from the users. I was able to see the number of emails being blocked as phishing or spam, and also some emails that were getting allowed, probably due to some configuration issue. That is how I derived the number. My review rating for Barracuda Email Protection is 10.

Email security has blocked attacks and provides reliable backups and detailed reporting
Reviewed on May 05, 2026
Review provided by PeerSpot
What is our primary use case?
I work with Barracuda Email Protection as a customer. My major use case for using Barracuda Email Protection is at 100% because we get the whole thing, but unfortunately, it doesn't do backup for us on-premises. It only backs up wherever it's stored. We have that kind of problem, but nonetheless, so far we can keep it because we haven't been hacked. It's blocking all malware, trojans, and all these things. It's doing well for us. We haven't had any attack on Barracuda Email Protection's side.
Before Barracuda Email Protection, we did use another product for backup internally until we found another solution for internal.
What is most valuable?
I'm using Barracuda Email Protection for backup and email protection for two purposes. There are also impersonation features and other capabilities, and most of it is acceptable, but the only thing I think that's missing is the WAF and some other features. Domain fraud protection is there, and it's quite comprehensive.
The biggest advantage for me in Barracuda Email Protection is that it's user-friendly, easy to navigate anytime, and the reporting is fine. Unfortunately, you can see all the message logs, which includes the inbound and outbound messages, and that puts it in a way that we feel like we can see emails that are too sensitive for management. That was one of the downfalls. If we could hide that feature, probably we could adjust the admin so we know one is accountable. But for now, once you give anyone rights, they have all the access to see the message logs and everything.
Regarding the threat protection feature in Barracuda Email Protection, it does not help to manage threats or sophisticated threats.
The reporting in Barracuda Email Protection is very good. You can do a weekly or monthly report, and it's excellent.
I find data protection in Barracuda Email Protection is adequate for us.
What needs improvement?
The downfalls I see are that it doesn't do backup on-premises, WAF is not included, and the issue with the message logs.
Something is missing in Barracuda Email Protection. I would like to see AI incorporation so that whatever AI platforms we are using should detect that something is not legitimate or whatever. If we can have that AI tool, the power tool of AI, that would be excellent.
For how long have I used the solution?
I have been using Barracuda Email Protection for three years.
What do I think about the stability of the solution?
I think Barracuda Email Protection is stable and very reliable. The upgrades they do behind the scenes keep us quite happy, with updates, patches, and everything.
What do I think about the scalability of the solution?
In terms of scalability, I would say it wouldn't be expensive to scale, but somehow it will take some other resources here in the operation of administration cost and management. Scalability is expensive for Barracuda Email Protection.
How are customer service and support?
The technical support from Barracuda Email Protection is helpful; you just need to know what you want from them. I would give eight points for support from Barracuda Email Protection.
Which solution did I use previously and why did I switch?
Before Barracuda Email Protection, we did use another product for backup internally until we found another solution for internal.
How was the initial setup?
In terms of installation and deployment of Barracuda Email Protection, I would say installation is quite easy. It's not complicated. It's just that it's tedious because a lot of things are involved, but immediately in an hour or two, you get to complete it. It's much easier if you are using the cloud one, but if you are using the on-premises component, that's one factor I feel is tedious. The cloud one is more maneuverable to deploy.
What was our ROI?
The investment in Barracuda Email Protection is quite good for us because we see the value of money on it. We are saving a lot with Barracuda Email Protection. In an estimate, we were paying close to 300,000, but now we are sitting with Barracuda Email Protection at 100,000.
What's my experience with pricing, setup cost, and licensing?
I would say the price for Barracuda Email Protection is very nice; the solution is not expensive.
Which other solutions did I evaluate?
I see a lot of differences between Barracuda Email Protection and other products. Darktrace is quite amazing, but the only factor I think you are much better with is the pricing, which is quite good. However, Darktrace is exceptional.
What other advice do I have?
I am not using threat protection in Barracuda Email Protection. I am not using link protection; it's only looking at the M365 ones. Even though I mention some problems like the message logs or the absence of WAF, I would still give Barracuda Email Protection the maximum score. I give this review a rating of 10.

Email protection has prevented ransomware and phishing and keeps our organization’s data safe
Reviewed on Mar 12, 2026
Review provided by PeerSpot
What is our primary use case?
We are still working with Barracuda Email Protection. The requirement for Barracuda Email Protection is to ensure security over all emails that come into the office, so it protects us from all malicious code, phishing, and ransomware attacks. It saves us from all of them, and it also tells us if there is a vulnerability in any user.
What is most valuable?
The functions in Barracuda Email Protection that I find the most valuable are the way it is reported and the way the solution is given for a threat if it has found one. The way it has protected malicious mails from being delivered makes a huge impact.
Threat Protection is a feature we use, which only gives us an advanced warning or an alert on any kind of malicious code coming in as an email.
Link Protection for email security is very important and very useful. We do use Link Protection extensively.
We do use Barracuda Data Protection functions, and the advantage we have is that the backed up data is protected from any possible attack that can come or any kind of hijack or data being misused. The Data Protection feature helps us ensure that the data is safe.
Barracuda Email Protection helps us prevent accidental data leaks because it gives Link Protection, so you don't click a link by oversight or mistake thinking it is genuine. This ensures that your chances of being vulnerable are gone, and the data used for protection is also safe, so we don't see any kind of data leak coming through this.
The main benefits Barracuda Email Protection provides for us are saving time and money because we don't run into any kind of attack or disruption in the mail service that we may face, including ransomware attacks. That is definitely important for us; the workflow is there but it is not that critical at this point. However, it is important to be protected and save money.
What needs improvement?
In my opinion, Barracuda Email Protection can improve by possibly adding more features towards zero trust capabilities or towards ensuring that the data protected is more secure, such as a vault. Additionally, the retrieval feature through Outlook, which is the email client that we use most, can be improved.
For the purpose for which we use it, I see no lack of function in Barracuda Email Protection. The wishlist can always be there to enhance it, but from what it is meant to do, it is fairly up-to-date and modern.
For how long have I used the solution?
I have been working with Barracuda Email Protection for about six to seven years.
What do I think about the stability of the solution?
For stability, I would rate Barracuda Email Protection almost a nine.
What do I think about the scalability of the solution?
I would also rate the scalability of Barracuda Email Protection as a nine.
How are customer service and support?
We have not had too many technical issues, but I would rate technical support as an eight. They can still improve.
How was the initial setup?
The setup process for Barracuda Email Protection is quite simple. We did the setup ourselves; our team installed it.
Which other solutions did I evaluate?
We did compare Barracuda Email Protection with other products, specifically Check Point Harmony. We chose Barracuda Email Protection over Harmony because we found Barracuda Email Protection's strike rate on identifying detection was much higher. Second, we found Barracuda Email Protection's pricing to be far more comparable and reasonable than Harmony. Additionally, I found the speed of Harmony was not as good as Barracuda Email Protection.
What other advice do I have?
I would give Barracuda Email Protection a final mark of about nine. We strongly recommend users to go with Barracuda Email Protection.
