    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.

    I feel the product is very good to set up basic standards and go beyond that in many aspects. However, due to being sometimes too simple, it limits the ability to do some other complex changes. Having the ability to do both would be ideal for some, if not all, of the products within Zscaler Internet Access. A simple setup to have it stand-up, and more advanced settings for those more experienced.

    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.

    • Provides a secure VPN connection point for endpoint connectivity.
    • Provides the VPN connectivity in a fast and reliable connection state.
    • Very dependable, once connected the connection stays up and there's no fuss.
    • Very good at letting you know when you are not authenticated.
    • Very easy to authenticate and regain access when your session times out.

    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.

    While Zscaler Internet Access (ZIA) delivers critical value in cloud security and RBI compliance, I rate renewal likelihood 7/10 due to evolving needs versus platform limitations. Below is my rationale:
    Key Gaps:
    1. Advanced Threat Costs:
    ZIA’s add-ons (e.g., Advanced DLP, Sandboxing) incur 35%+ cost premiums – straining budgets as transaction volumes (UPI/iMobile) grow 50% YoY.
    2. API Banking Scalability:
    ZIA’s API rate limits throttle real-time policy sync during UPI peaks (10K+ TPS), forcing workarounds for finacle integrations.
    3. RBI Future-Proofing:
    Limited native support for upcoming digital rupee (CBDC) security rules requires custom development, increasing compliance overhead.

    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.

    Getting started was pretty straightforward. We can tell the product is way more robust than we are using it. It started as a replacement for previous DNS-blocking content filtering, but we're exploring how this will add value with an upcoming DLP redesign and with traffic optimization at some of our remote sites with severe bandwidth limits.

    Performance

    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.

    Zscaler's ZIA support is quick and knowledgable. They respond within 1-2 hours of you submitting your ticket. They are very thorough and are typically ready to jump on a live troubleshooting session. Our ZIA platform and how we use is it unique so at times tickets can be open for weeks but we alway get quality support compared to other unrelated product support in our enterprise

    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

    The overall user community and scope of supportability outweighed the others on our short list. Netskope was a close second, but the risk, though small, was greater than that of bringing Zscaler aboard. We were looking for a mature, well-supported, highly functional, and fine-grained solution that met all our user and information security requirements.

    Contract Terms and Pricing Model
    Cisco
    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.

    - 8 out of 10 and took 2 for the data pipeline and administration part. Even if you'd like to improve yourself or your team, you have to pay a lot of money and it could be more than GIAC education + cert. - Normalization for Data models and CPU-based searches can be a problem sometimes.

    I had a fantastic experience with Splunk Professional Services: they worked with us in our last SON project (a SOC migration for a very large customer) and helped to build a multi tenent environment even if ES isn't a multi tenant platform. Th Splunk PS was a very professional and competent people, he is italian and was able to speak with our italian customers.

    Return on Investment

    • 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.

    • I would say it has a very good ROI, as whenever someone can't access something, they submit a ticket to our network engineer, and within minutes, the site is safely added to ZIA with best-practice configurations. After seeing a little of the UI from the Zenith event, it seems very user-friendly to control these policies.
