PROS

Zscaler Internet Access excels in providing robust security protection from anywhere, regardless of the organization size, with continuous cloud updates.
The centralized single panel allows efficient management and visibility for configuring security policies across an organization globally.
After proper implementation, maintenance demands are low, while the scalable architecture aids in seamlessly replacing traditional on-premises solutions.
Zscaler Internet Access enhances security through features like DLP, bandwidth control, and SSL inspection, effectively reducing cyberattacks and protecting data.
Its deployment is straightforward, and it integrates well with existing infrastructure, supporting various security controls while ensuring low latencies.

CONS

Zscaler Internet Access pricing is considered high, making it less accessible for smaller businesses and users concentrated in one location.
SSL inspection with Zscaler Internet Access can lead to performance issues due to inadequate implementation of ciphers.
Integration with other applications needs improvement, often requiring users to apply manual bypasses due to strict restrictions.
Technical support response times and problem resolution need enhancement, especially for complex cases.
Limited troubleshooting capabilities and insufficiently informative logs affect administrative control and error resolution.

All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote. I have greater control site access and I minimize the number of compromises that we experience to almost none.

The scanning feature is impressive, because they do not introduce a big latency to the traffic.

The initial setup was straightforward. The biggest thing for us was to build our own policies. The deployment itself was only a few hours.

The best thing about Zscaler Internet Access is the website filtering. In the UAE it's quite an important feature because most of the malware comes through the SQL injection and through downloads from websites. Zscaler helps protect against that.

​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​

The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market.

It needs better integration with other applications. It takes a fair amount of regular activity to apply the by-passes because it is very strict in its restrictions and frequently you have to go in and open things up to allow the workforce to work.

Another thing that I would like to see is if Zscaler could have a separate product for direct access. I looked at a private access solution, but I understand there's a separate product that isn't integrated with this.

It also needs better integration with other applications as well. There are some restrictions.

I would like to see the ability to choose a pool of IPs for my company, set up rules based on them, and know that those IPs are not used by other companies.

In every cloud service in the world, you have multiple upstream internet providers to create diversity so that if one of your providers fails, your network just continues. In South Africa, there is only one upstream provider, and that's not right. That that's a problem.

In terms of usage, here in the GCC, it's still growing a growing market, so the combination of DLP, data leak prevention, to a certain extent is fine. But what it requires is user-based access or role-based access. The solution needs to grow into that, which definitely takes time. There's not an easy way to integrate it, when you have a cloud-based solution.

Zscaler should provide adjacent services, which would be complementary to their current offering that could to be more pragmatic for a customer. For example, if you take Akamai, you get multiple sets of services, all depending on the customer and the strategy and the complexity and the problems. In some areas, they are more varied in terms of coverage.

I don't know whether it's Zscaler or not, however, sometimes I can't access my time management. I need to wait and try again a few hours later. Typically, if I let some time pass, I can access it again.
