What is our primary use case?
We use DLP to monitor network traffic and prevent sensitive data from being exfiltrated outside of the company. Symantec also helps us discover data at rest in an environment that may be sensitive. The solution covers more than 10,000 users across various business units and layers, including endpoints, networks, and storage.
How has it helped my organization?
DLP is a control instrument for ensuring that an organization complies with regulatory requirements. For example, banks have requirements for storing credit card data, GLBA regulations, etc. DLP can help a bank avoid fines and protect it from civil liabilities.
Companies are audited annually, and DLP improves their risk posture. It ensures business operations won't get shut down because we don't know what we don't know. There are also internal threats, such as people leaving with privileged information on a USB. For instance, an earnings report could be stolen by a disgruntled worker and leaked to competitors. Symantec provides good definitions in the rule set. It can be customized to scan inside documents and pattern-match any unstructured data to comply with what the company needs.
What is most valuable?
The data-at-rest features are the most valuable because they let us identify data infected with ransomware and prevent employees from being exploited through phishing attacks. If an employee is compromised, the attacker can access servers and deposit ransomware. This enables the attacker to exfiltrate data remotely using employees' credentials. It might be valuable data that could cause a business reputational and financial damage if stolen and publicized. It could also be credit card data or personal health information stored on critical servers.
The false positive rate is excellent. It's about 90 percent accurate and gets better as we fine-tune the rule sets. When we have new incidents, we can work to lower the overall risk based on user behavior on the endpoint, the kinds of data we out on SharePoint, and the type of web or FDP traffic generated internally. I assess the effectiveness of a policy based on the number of false positives generated. We need to tune the rule set if it's greater than 20 percent.
The solution's data recovery is fast. It depends on the size of your storage, but I have no complaints about the speed of data recovery because there are several detection servers with the necessary horsepower to handle the amount of data that needs to be discovered. It could be remotely scanning a SharePoint server or a file server. The local agents can process data in the expected timeframe.
What needs improvement?
The upgrade process is convoluted. The server and database software must run in line with third-party providers like the Oracle database. If an Oracle database reaches the end of its life, then servers must be decommissioned, and you need to bring new servers online.
When the maintenance packages are deployed to the management server, they don't get pushed to the detection servers. Each detection server must be manually installed rather than automatically made from a single server. If it's a large enterprise, you need to manually install it or use a GPO or some other technology, which I never use.
The vendors should also give a heads-up long before updates are released so internal teams can meet their change management lead times. Some vendors don't provide enough notice. They often announce a new version or a vulnerability that needs patching a week before it comes out. It should be a month before.
The upgrade packages should have better documentation on the upgrade procedure instead of prerequisites spread throughout multiple documents. The wording should be more precise.
For how long have I used the solution?
I have used the solution for ten years.
What do I think about the stability of the solution?
Symantec DLP is highly stable. I've operated on Linux and Windows. Linux is stable and doesn't require much patching, but Windows requires more patching, and the service sometimes needs to be restarted.
What do I think about the scalability of the solution?
Symantec DLP has unlimited scalability if you buy enough licenses. Symantec has servers in the USA, Canada, Asia, and Europe that manage policies differently. For example, Europe has its own compliance rules for GDPR. Incident response can be managed well and segmented away from the rest of the world. You can implement Europe-specific policies.
How are customer service and support?
I rate Symantec technical support a seven out of ten.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
I previously used an appliance called Websense to analyze traffic for data loss. I used other Broadcom tools before Broadcom bought Symantec called Broadcom Proxy and CloudSOC Gateway. I didn't switch from Websense to Broadcom. It was just something I tried, so it wasn't a full deployment. Symantec DLP is head and shoulders above the competing on-prem DLP solutions.
How was the initial setup?
There are a few tricky parts when setting up Symantec DLP, but it's straightforward overall. We used an integrator for the deployment and didn't experience any hiccups after they were finished. About ten people from my company were involved.
We have two or three people doing maintenance on the solution, like weekly health checks to ensure services are running and traffic flows through the console dashboard. We need to check the incidents generated from the detection servers and verify that everyone can log in. The main part of maintenance is periodic system updates and vulnerability patches.
What was our ROI?
We see an ROI. During testing, I found it captures and blocks immediately. DLP is able to perform the necessary alerts. We can work with the business and get them on board to see what kind of data they use. We can assign the right roles and manage each business to assess its performance in terms of data loss. Symantec enables us to generate reports to show if their security posture or data loss is changing over time. It's a valuable tool that does what it claims.
What's my experience with pricing, setup cost, and licensing?
The price of Symantec DLP is fair. I don't recall the cost of the license, but it wasn't outrageous enough that it was an obstacle to approval. I'm not concerned with how much per seat or server, but I know they charge a lot.
If you're thinking about going for a cheaper solution, I suggest a close comparative analysis of the strengths and weaknesses of each solution by researching online and reading the vendor's documentation. You have to define your security requirements and look at factors like false positive ratios and whether it meets your compliance needs. Some companies only need to meet the minimum regulatory requirements, so a cheap solution that ticks all the right boxes might work. However, if security is the primary goal, you should compare the strengths and weaknesses of that cheap vendor against two or three other DLP vendors.
Which other solutions did I evaluate?
I didn't evaluate other solutions before choosing Symantec DLP this time, but I evaluated other DLPs for different projects. However, those were cloud-based DLPs, so it's not an apples-to-apples comparison.
What other advice do I have?
I rate Symantec Data Loss Prevention an eight out of ten.
