Zscaler Private Access™ (ZPA) gives users secure access to private apps and OT devices while enabling zero trust connectivity for workloads.
Vertica as a data warehouse to deliver analytics in-house and even to your client base on scale is not rivaled anywhere in the market. Frankly, in my experience it is not even close to equaled. Because it is such a powerful data warehouse, some people attempt to use it as a transactional database. It certainly is not one of those. Individual row inserts are slow and do not perform well. Deletes are a whole other story. RDBMS it is definitely not. OLAP it rocks.

Zscaler Private Access works really well in environments setup for FQDNs and where you know what users should/shouldn't be accessing on what ports. You can use Zscaler Private Access to figure out these kinds of features but that doesn't always mean you'll be correct. It also provides a consistent experience for users as they can access their materials anywhere. It also makes the user the last line of defense. If a user's account is compromised then the attacker has access to everything they already did. It doesn't work great in OT environments or Server based environments. Flows have to be initiated from the client and not the server for stuff to behave properly.

Connecting users remotely with a secure connection. I am a service desk agent who works with end users, and if there is an issue due to ZPA, it's most likely due to configuration. A really good service.
Logging, I believe, works well as I troubleshoot end users and can gather extra details for my network admin. IP.zscaler.com, and the debug logs are nice. Additionally, I like how it shows the App policy assigned to the user's machine ECT.

Could use some work on better integrating with cloud providers and open source technologies. For AWS you will find an AMI in the marketplace and recently a connector for loading data from S3 directly was created. With last release, integration with Kafka was added that can help.
Managing large workloads (concurrent queries) is a bit challenging.
Having a way to provide an estimate on the duration for currently executing queries / etc. can be helpful. Vertica provides some counters for the query execution engine that are helpful but some may find confusing.
Unloading data over JDBC is very slow. We've had to come up with alternatives based on vsql, etc. Not a very clean, official on how to unload data.

Needs an interface for Support Desk/Help Desk to more easily understand that the problem is a lack of an FQDN or access is not allowed due to policy, not because of a technical shortcoming in ZPA.
Documentation of the BC solution is not well-detailed.

The environment feels more secure, and we are seeing that users are adapting to it fast. The fact that we have tools to assist the users with their day-to-day access helps, as we can hand it off to the helpdesk without any escalations to the Network team. It is a work in progress for our agency, but we are seeing the benefits from the solution.

I haven't had any recent opportunity to reach out to Vertica support. From what I remember, I believe whenever I reached out to them the experience was smooth.

Vertica performs well when the query has good stats and is tuned well. Options for GUI clients are ugly and outdated. IO optimized: it's a columnar store with no indexing structures to maintain like traditional databases. The indexing is achieved by storing the data sorted on disk, which itself is run transparently as a background process.

ZPA is where the bulk of zero-trust access is found. While the functionality for ZIA is excellent, the policy we implement for internet access is more focused on threat prevention and not narrowly scoped access.

We used to get anywhere from 30 to 50 tickets surrounding our previous VPN solution every month. We now average 3-5 tickets regarding remote connectivity, and of those, only 1 or 2 are actual issues with ZPA.
Using ZPA Access Policies, we can now block endpoints that have outdated security software from ever connecting to our environment. This was simply not possible with our previous solution.
Some of our employee base skews older and had a harder time understanding the change from VPN to Zscaler.
There is significantly less downtime with ZPA when compared to other VPN solutions.
