Sentiment score

The technical support from Darktrace is of high quality.
Darktrace provides excellent technical support with a monthly meeting to review platform incidents, ensuring the system functions as expected.
The challenge lies in waiting for a response after logging a ticket.
Support personnel are hesitant to engage in remote sessions, preferring to share documentation via email.
Mimecast technical support is generally quite good.
 

Scalability Issues

Sentiment score
7.6
Darktrace is praised for its scalability, seamless expansion, robust architecture, and capacity to manage increasing demands effectively.
Sentiment score
7.5
Mimecast Email Security is scalable, adaptable, and allows easy license adjustments but may face occasional feature challenges.
Darktrace has high scalability, and I would rate it a nine out of ten.
Since it's cloud-based, it expands easily.
There is still a gap in terms of storage, and we are trying to figure out how to increase that capacity for regulated environments, which require data retention for 5 to 6 years.
 

Stability Issues

Sentiment score
8.5
Darktrace is praised for its reliability and stability, offering seamless performance and quick resolutions to occasional issues.
Sentiment score
7.7
Mimecast Email Security is praised for stability and integration, with rare downtimes, few bugs, and high user satisfaction.
The stability of Darktrace is excellent, rated ten out of ten.
The appliance itself has never let me down.
For stability, I would rate Darktrace an eight out of ten.
 

Room For Improvement

Users seek better SIEM integration, improved automation, user-friendly interfaces, and enhanced protection with more intuitive reports and dashboards.
Mimecast Email Security struggles with detection, user interface, support, costs, configurations, and database reliance, affecting overall user satisfaction.
There is no dedicated salesperson in Egypt, and having one would help to improve focus on this market.
They say they can integrate with most firewalls, but when we did an integration with Meraki MX firewalls, that integration didn't work and still doesn't work to this day.
We need Darktrace on each branch to get the data out, and I suggest having some kind of a centralized product that gets data from multiple sources to aggregate and provide the data.
A lot of emails were missed despite being known samples.
 

Setup Cost

Darktrace offers flexible payment options but is costly, especially for small businesses, justified by its advanced features.
Mimecast Email Security is seen as costly, though features and updates justify the price; competitors offer cheaper alternatives.
The product is considered expensive compared to others.
The pricing is costly in USD, and they charge based on device counts.
The licensing cost is approximately eight dollars a year.
The pricing is higher for Mimecast, particularly for the Indian market, where it is considered expensive.
 

Valuable Features

Darktrace provides AI-driven security with fast responses, real-time monitoring, and autonomous threat management, minimizing false positives efficiently.
Mimecast Email Security excels in threat protection, spam filtering, and user-friendliness, with strong Microsoft 365 integration and technical support.
It is capable of responding to lateral movement and ransomware deployment within environments where there is data exfiltration.
I do not need to manually process incidents as Darktrace provides an incident summary, potential detection paths, and other details, all exportable with just a click.
If I am in a data center where I don't have layer two, it becomes an issue because the autonomous response is reliant on sending spoofed TCP resets to my core switch to block traffic, which is a major issue.
A distinct advantage of Mimecast is its ability to block phishing and impostor attacks, which are significant threats currently.
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.

Featured Reviews

Malebo Lethoba Group - PeerSpot reviewer
Have found the AI analyst and detection functions highly valuable for network operations while managing complexity in initial setup
The functions I find most valuable in Darktrace ( /products/darktrace-reviews ) are the AI analyst as well as the detection.The autonomous response capabilities of Darktrace are not crucial for me because it doesn't work in a network where there are no core switches. In a modern network, the autonomous response doesn't work, especially when sitting in a shared data center.If I'm running a traditional network where I am not in a shared data center with a layer two dedicated for my resources, then it can work for me. However, if I am in a data center where I don't have layer two, it becomes an issue because the autonomous response is reliant on sending spoofed TCP resets to my core switch to block traffic, which is a major issue.
ShaheenKapery - PeerSpot reviewer
Provides valuable security features and has a straightforward setup process
The initial setup process is straightforward and takes a weekend at most. A .com domain can take up to forty-eight hours, while a local domain takes about four to eight hours because it has to propagate through the international DNS records. It is a cloud-only solution. If you're managing email security on-premises, you use your bandwidth to download emails, including spam, and then use your servers to clean it up. For example, say a third of your email is spam; this consumes significant bandwidth and resources. However, if you use Mimecast, they filter the emails on their servers before delivering them to you. It can be a major selling point in regions with expensive bandwidth, such as Africa. You can save bandwidth and improve overall efficiency by offloading the spam filtering to Mimecast.
