Enhances web security with a single pane of glass and flexible deployment

I don't see any need for improvement; one of the really good things about iboss as a company is that they listen to customer feedback. I have suggested enhancements, and they are responsive, making changes for the better, and they do a lot of testing. To improve iboss, although we haven't used it, we considered the VPN solution that comes with the highest tier licensing, which includes DLP and various other add-ons. We prefer using another product which automatically logs you back onto your network when turning on your PC. With iboss, the connection is manual, which doesn't meet our needs. Additionally, sizing can be tricky because, although the initial recommendations may seem adequate, actual usage may require more gateways than anticipated.

Ensures comprehensive protection with seamless threat logging and efficient policy management

My favorite feature of Cisco Umbrella is probably just the DNS and the fact that when a security threat happens, all of that gets logged in their Umbrella portal, and it's very easy to find who's been accessing the site and how many people have accessed it, so that we can go to them and make sure they're not compromised. The features of Cisco Umbrella benefit my company by providing less time to search for things through logs, to look for what we need. It's just one place to go, and we just search for it, and we find it really fast. The fact that there's a virtual database that has all that information is great on our portal.

Seamlessly customize security features but need improved deployment speed

I find Fortinet FortiCASB easily customizable. It allows me to leverage features that cover almost eighty percent of use cases required by my clients. The compliance management feature supports GDPR and HIPAA compliance, effectively meeting those use cases. The hybrid model of Fortinet offers seamless deployment on cloud or hybrid best suited for customers, making it adaptable in various scenarios.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The solution has massively improved our security posture, giving us full visibility into what our staff does online."

"The console is cloud-based, which is something I really appreciate."

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."

"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."

"The iboss system is highly reliable. The false positive rates are small compared to some other systems we've experienced through other partner agencies who use competing solutions."

"From a corporate perspective, I understand that it's important to keep the company data safe."

"iboss is definitely very good in terms of service."

"From a use-case scenario, what I like the most is the plug-in. I like the fact that we can do the filtering of these devices offsite independent of the network they are connected to, and we do not have to have traffic coming back inside our network."

More iboss pros

"It has improved our organization from a security posture perspective, and we feel more confident now knowing that we can block phishing attempts or any type of malware that is DNS-related, which is a very nice feature that provides peace of mind."

"DNS protection, domain blocking, SIP component, and the Cisco Umbrella roaming client are the valuable features of Cisco Umbrella."

"It's very stable, reliable and does its job."

"The solution is extremely stable. It has excellent performance."

"We are very new users of the solution and are still in the exploration stages, but we are happy with the product thus far."

"The core business of Cisco Umbrella is non-malware. That's all it does: block the malware on the gateway."

"For us and for customers, it's the ease of integration with Meraki. It's just a couple of clicks. That allows us to deploy very fast, and it doesn't change the way a customer uses his service. It's just more secure."

"Cisco's support is fantastic, providing assistance when needed, especially during the initial installation process."

More Cisco Umbrella pros

"I find Fortinet FortiCASB easily customizable."

Cons

"To scale up, a new iboss Node Blade Chassis must be purchased."

"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."

"The dashboards for local use could be better."

"One thing I would like to see differently with their Zero Trust platform is that some of the AI aspects related to high-risk activities have more false positives."

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."

"Sometimes the agent stops working in iboss, and we have to reinstall the agent."

"Their on-premise hardware's network interface is capped at one gigabit, which is sort of a problem. If you stand a filter up where all traffic flows through that, according to them, in order to go above a gigabit, you have to have multiple devices, which in today's IT seems a little bit silly. They could easily put in an SFP port into their device that could accommodate 10 gigs or at least offer a box."

"Sometimes, obviously, there are bugs."

More iboss cons

"The different levels of security, such as backend security and internet security, need improvement."

"I would like to see more integration between Cisco Umbrella and Cisco DNA Center."

"The detection of wireless attacks or targeted attacks reports many false rates. This is an area that needs some improvement."

"The firewall capabilities could be better. Cisco is starting to introduce some layer 7 capabilities now, but there's still some room to grow. They should continue with the development of Umbrella so that it is a full-blown cloud-managed firewall solution."

"Missing a real data leakage prevention solution."

"When I looked at it, it was impossible to manage app control."

"iOS devices and mobiles are huge in my environment right now, and I cannot run them on Cisco Umbrella 24/7."

"Looking at the full umbrella suite in the light of SASE, Secure Access Service Edge, they are clearly lacking in the inline CASB."

More Cisco Umbrella cons

"The turnaround time to deploy Fortinet FortiCASB could be improved. The learning curve for deploying, configuring use cases, and rules can be better."

"The turnaround time to deploy Fortinet FortiCASB could be improved."

Pricing and Cost Advice

"It is expensive compared to one of its competitors."

"It is probably in line with other solutions, but I do not deal with the financial side."

"We had the cost of purchasing a new appliance along with the implementation and licensing costs. However, the following year, the cost of just licensing was similar to what was paid the previous year for a new appliance along with the implementation and licensing costs."

"The overall pricing for iboss is very competitive and transparent."

"It is not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."

"We have not priced the solution recently, but they were competitive with other vendors in the past."

"The product is pricey compared to Cisco Firepower."

"Pricing and licensing of Cisco Umbrella is a bit confusing because you have to separate the DNS solution and the full-feature solution. Cisco in Portugal helped us understand which one was the right one for us."

"The pricing is pretty fair. It's good."

"I rate the tool's pricing a five out of ten."

"Cisco Umbrella is expensive and could be cheaper."

"It has a reasonable price. It is certainly not as expensive as it used to be. It is in line with other offerings on the market. There are a number of different flavors of Umbrella. They could bring Umbrella SIG down a bit because its price is a little bit high for what it does, but I also understand why its price is high."

"You get what you pay for."

"Cisco should make the solution cheaper."
