    Chose Tenable Nessus
    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.

    Fortinet FortiGate addressed an immediate security issue we had a few years ago. The device gave us a much clearer picture of the activities on our network and also more importantly, increased our awareness of threats from the internet as a whole. Fortinet FortiGate helps us to mitigate these threats with regular signature updates from Fortiguard labs, identifying certain characteristics which, once recognised by Fortinet FortiGate, can be harnessed to deploy powerful 'playbooks'.

    It is an excellent tool for scanning servers, workstations, and network devices to identify missing patches and misconfiguration; we regularly use it to confirm patch effectiveness after the update; it also helps us for preparing audits such as iso 27001, and regulatory requirements, it also helps us to identify open ports and services that violate security.

    Pros
    Fortinet
    • SD-WAN - Load balancing of Internet traffic is a USP of Fortigate and makes it stand tall in the competition. Be it 3 or more Internet Links, multiple Subnets/segments of users to distribute and bandwidth load balancing for links and users. SLA based monitoring of Internet Links / MPLS links, makes it even better to choose the links on the basis of performance (Latency, packet loss, Jitter etc).
    • SSL VPN configuration - As we all have WFH force (to some extend or all employee) during Covid-19, it is impossible to plan BCP without having a SSL VPN. In Fortigate, the SSL VPN configuration is very easy with the help of wizard. The deep CLI-level debugging is also very helpful in troubleshooting. Type of tunnel can be easily configured - Full Tunnel or Split Tunnel for SSL.
    • Explicit Proxy - This is also a great feature to shape and re-route the traffic, configuring the Proxy on the Firewall itself. We are using this feature in Pilot for now, and planned to rollout in few weeks looking at the success rate of the POC.

    • Nessus is best at performing vulnerability scans, in fact, it gives findings and moreover accurate findings of the assessments. It does not do penetration testing or exploit the vulnerabilities because it is concerned about scanning the systems/applications.
    • In fact, Nessus has multiple profiles/policies to perform different types of scans such as, scans oriented for PCI-DSS, malware scans, web application scans, bad shell shock detection scan to name a few.
    • Nessus has the ability to classify the vulnerabilities into risk-based categories from critical to even informational which I think is one of the things that separates Nessus from other vulnerability scanners.

    Cons
    Fortinet
    • Documentation is missing a great deal of detail and assumes the customer and just guess and fill in the blanks themselves
    • Fortinet has lots and lots of video guides on topics that only a small percentage of customers would ever need
    • The documentation and video guides do not get updated so most is only relevant to older software versions

    • The tool has lots of options for setting up before scanning any device, this methodology could be simplified further with default configuration for various devices predefined, anyhow we can use this technique by making use of policies.
    • For advanced users we cannot disable the plugins inside the plugin groups, we can enable the whole set of plugins at a time, for few hundreds its ok, but thousands of plugins are of waste of resource and time.

    Usability
    Fortinet
    The firewall runs very well, firmware updates are fairly quick but you must follow the upgrade path. Neglecting this step will cause a lot of pain. If you decide to go with Fortinet FortiGate switches and/or access points, they can be managed within the firewall which is great. We're also using the FortiAnalyzer which easily plugs into the firewall for any reporting you may require.

    Tenable Nessus is a great product and provides a lot of value, but it is difficult to set up and use and the amount of data it generates can be overwhelming. It does help us prioritize based on the severity of the detection, however there are sometimes mitigating factors that we have implemented that Nessus does not account for, which causes lots of noise in the reports.

    The Support team at Fortinet is excellent. They can not only help you configure the device for what you are trying to do, they offer suggestions on improving rules, and troubleshooting issues. Their response time is fast, ensuring you are up and running immediately with no questions asked. We had a hard drive failure in one of our Fortinet Fortigate appliances. The tech answered immediately, and started rebuilding the drive after some preliminary investigations. After rebuilding, there were still errors and issues, so they dispatched a brand new Fortinet Fortigate appliance. The tech then backed up the configurations for when the new device came in, which showed up in a few hours. A restore of the configuration took less than a minute, and there were no more errors or issues.

    [Fortinet] FortiGate is not only cost effective but it gives the comprehensive security against the APT attacks and gives the complete traffic visibility and granular control. You can easily create the VDOMs (Virtual firewall) within a Fortigate firewall and customize the dashboard as per your requirement if you have multiple VDOMs within a single firewall.

    Return on Investment
    Fortinet
    • The pricing given to us for our firewall was well within what we were already spending for other vendors solutions and had the added value of eliminating a separate expense for a dedicated web filtering appliance.
    • We have also adopted Fortinet's security fabric approach and thus changed vendors for our switch and AP devices. These devices have come at reduced prices as compared to another previous vendor we were using, particularly in relation to ongoing annual maintenance costs.

    • 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.
