Darktrace

I think if you manage a large number of mailboxes, you need a reliable solution to protect corporate email from any threat. This solution uses AI to analyze emails to check if they're safe or if it's a risk for the organization. It has a good UI (all in English), and the more you're using it, the more you get. There are a lot of metrics and indicators to help the email security admin.

Nessus is perfectly suitable for performing comprehensive vulnerability assessment scans being a vulnerability scanner. It is less appropriate for performing penetration testing since it is not a penetration testing tool, it does not have the ability and modules to exploit the vulnerabilities of the system.

Pros

Darktrace

  • Monitors your network for unusual behaviour; as it learns what is normal for your network, you don't need to worry too much about things that are normal for your organisation, but might be considered odd in other places, triggering as alarms. It can also detect more subtle changes such as a device accessing a server but at an unusual time.
  • There are a large number of models that are used to create the alerts, which can all be customised, and you can also create your own from scratch, to allow you to tailor it perfectly to your situation.

Tenable Network Security

  • With Nessus we can find the missing critical patches for a server or workstations.
  • Nessus points out any vulnerable or outdated software Technologies used in the system, thus eliminating any chances for security flaws being turned up.
  • Nessus typically points any configuration level issues in accordance with the OWASP guidelines. Even the configuration of SSL related which are most of the time handled by some vendors or 3rd parties.
  • Nessus not only lists out these Vulnerabilities but describes clearly the vulnerabilities in details with its thousands of plugins updated regularly, the tool also recommends solution with practical details of easy implementation.

Cons

Darktrace

  • Really had a poor time of identifying devices and what the device's purpose was - a simple nmap scan did a better job. The problem is they expect you to fine-tune the results - which is exactly what you would expect - but day one it found over 2,000 servers (and I only have 112).
  • Really had a hard time separating network traffic into locations - I use distinct subnets for my buildings, but there was no good way to create a logical map of my traffic internally. Did not garner a sense of trust that it was seeing everything.
  • Sat through a few "analyst" reports - which showed me possible threats in my environment. I am already using a few open source tools, and they actually found more than the analyst reports. Also, there was no way to get the reports on your own - you had to work through their analysts to get the information.

  • Could use an upgrade within reports.
  • Scans can take a long time to complete. Have to break them down in small sections.

    Nessus is best and easy to use application for Vulnerabilities finding and reporting, it has multiple platforms and wide scope covering almost all devices for security improvement so far, thus we are very likely to continue its services.

    Support Rating

    Darktrace

    Darktrace support is excellent in my experience. They send a competent engineer on-site to provide on-boarding training. They were also very responsive in responding to questions and concerns. Having an individual point of contact who is a competent network and security engineer is not a common experience, at least for me.

    I haven't needed to contact support yet. But issues are easily solved with a quick internet search which means support and by extension, the larger community are involved and knowledgeable.

    Alternatives Considered

    Darktrace

    The Darktrace user interface was improved. Darktrace provides more metrics and more info to decide if an email is malicious or not in doubt case. Darktrace provides a lot of info about the email being analyzed, if there was a previous communication between both parts before for example, it's so easy to deploy.

    Sometimes when we identify a vulnerability with Nessus that has an exploit, we made a proof of concept with Metasploit in order to show to the IT managers the importance of the software/hardware hardening.

    Return on Investment

    Darktrace

    • Darktrace is covering some lack of security issues.
    • Darktrace helps the company to follow some compliance obligations.
    • Darktrace can't solve all issues. It needs to work with other Security tools (e.g Splunk).

    • Nessus certainly has a positive impact while me while performing my job, either as security research, or performing vulnerability assessments for clients. It gives a lot of information about the system/application after performing scans. The number of false positives is also less compared to other vulnerability scanners.
    • The professional edition is very useful as policy templates available in this edition are very handy and useful even to perform compliance scan like PCI DSS scan.
    • Also, the ability to export the scan results into reports in formats like HTML, PDF is very useful which could be for performing system/application reviews.
