    Based on my experience, Splunk is a strong git for some environments and a poor match for others. The distinction is primarily based on infrastructure complexity and budget. It's perfect for large enterprises with a mix of on-prem/cloud infrastructure. It's not a perfect match for small teams with restricted resources.

    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
    Cisco
    • Writes Powerful Queries: The queries that can be written using the Splunk Query Language are very powerful and highly customizable to meet every need. Ex: Writing queries to search the intersection of two different sources like Network and Endpoint Logs.
    • Offers Dashboard Abilities: Helps build complex panels for Dashboards in addition to providing several out-of-the-box panels. Ex: creating panels to calculate the performance of analysts in a given timezone.
    • Helpful Search Aids: It helps to set up complex custom alerts very easily. The interesting fields section is very helpful while threat hunting. Ex: It shows all the users and the frequency of each in a failed login event. The user list on the interesting fields is useful to look for suspicious logins.

    • 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
    Cisco
    • Improved User Interface Customization: While the interface is generally intuitive, providing more options for users to customize their dashboards and views would enhance the overall user experience. Tailoring the interface to specific roles or use cases could be a valuable addition.
    • Simplified Alert Management: Streamlining the process of managing alerts, such as grouping or categorizing them based on severity or type, would make it easier for security teams to prioritize and respond to incidents effectively.
    • Expanded Threat Intelligence Feeds: Increasing the variety and sources of threat intelligence feeds available within ES would provide a broader context for identifying and mitigating emerging threats, ensuring a more comprehensive defense against evolving attack vectors.

    • 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
    Cisco
    Maintaining hundreds or even 1000+ SOC use cases is really difficult, considering that the Data sources may not always send the data. A module that detects data freshness issues and detect data format changes would be a great help. the main challenge today using Splunk Enterprise Security is making sure that the detection rules are still working properly given all the changes that occur in data source applications. Also, maintaining the data collects on tens of thousands of servers and more than 100k workstations is a real company IT challenge: the splunkbase forwarder may not support old OS anymore, while these are the most important to monitor. Moving to the Open Telemetry collector has become essential so that only 1 agent is required for both SIEM and application observability.

    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.

    It takes a long time for items to load if you are just generally searching through logs. It is best to use the data models which load faster but can be strange in terms of what is coming from which logs where. Yes, you can look it up, but this also requires familiarity with where things are and how to look them up.

    It's good when it's responsive, but I've had times where I had to wait quite a while for a response. But these are typically the exceptions rather than the rule. When you do get a response it is always well-informed and appropriate. I would say they've been trending better over time with this.

    I experienced only on-line training, but the trainers were very professional and competent. Maybe it could be more useful if they also have an experience in projects because sometimes they didn't have a real project experience to communicate to the students. Anyway, it was very interesting and I learned many thing that's very difficoult (or maybe impossible!) to have by myself, aven if I have more than 10 years of Splunk activity experience.

    It was very interesting and I learned many thing that's very difficoult (or maybe impossible!) to have by myself. The only problem was that, when I worked with the Splunk Professional Services, I found some difference between the training contents and the information from PS. In addition is required a long experience on Splunk Enterprise for the data ingestion part, in other words I'm able to work with ES because I'm worling on Splunk since 11 years, otherwise I'd some problem.

    Splunk enterprise is the only solution that we’ve been able to identify that provides risk based alerting, which allows our SOC to reduce analyst fatigue which would be a huge problem without it. Before RBA, there were thousands of alerts a day and it was impossible to review all of them

    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.

    for my exterience, unit pricing and billing frequency are correct. As I already said, I hint to have more discount flexibility, expecially with new customers, because there are competitors less expensive and very aggressive that are dangerous. In addition the possibility to don't pay the license for the development period could be a very interesting feature for the final customers.

    • We have a 100% success rate on all our ES implementations due to the amazing documentation and Splunk enablement on the subject.
    • Our Splunk ES business has grown 100% YoY for the last 3 years.
    • In terms of long term management and maintenance, ES has been highly stable and predictable, reducing our overhead on costly services team for ad hoc maintenance work.

    • 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.
