It's easy to roll out, and their understanding of our business made it seamless
One aspect we value about iboss is its simplicity. Their customer service is brilliant, and they are super responsive and knowledgeable. It's easy to roll out, and their understanding of our business made it seamless. We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times. The user interface is highly intuitive. Our IT team picked it up with minimal training. It's arranged so that it's easy to find where things are. Another advantage is the single pane of glass console, which gives you visibility into what's happening. We're not fully there yet because we haven't implemented zero trust, but we're excited about the possibilities from the demos we've seen. We launched a POC of iboss' ChatGPT Risk Protection feature two weeks ago. AI is a great tool, but you need to be careful what you put into it. My biggest fear is employees inputting sensitive corporate information or customer PII data into one of these chatbots. I was impressed by our trial of the feature. It's exactly what we wanted. Now, when a user goes to ChatGPT, there's a banner warning them not to share information, and we can block conversations containing customer data like bank details and email addresses. I don't want to stop people from using it, but we need visibility. We've only tried it on a test group of 15 people. You can configure it to look for specific keywords or integrate it with your DLP policy if you have that configured

Helps reduce the risk of a breach and is easy to deploy and onboard
For our customers, Duo Security is a significant advantage because it provides them with a straightforward method to implement MFA across their entire environment. Moreover, once we delve into the more advanced features of Duo Security, it enables us as a partner to engage in ongoing discussions regarding security strategies with our customers. Initially, we may only introduce them to MFA during the onboarding process. However, as their security strategy evolves, we can leverage Duo to perform additional tasks such as risk-based assessments and deployments, thereby assisting in the development of their security measures. Duo Security helps secure our infrastructure. It serves as our gateway layer of protection, allowing us to understand who is logging in and why. We conduct risk-based assessments on each user to determine whether their actions are appropriate or not. Duo Security is not a comprehensive security solution, but it is undoubtedly a crucial component, a critical layer of security. This aspect resonates with our customers consistently. Their ability to reduce the risk of a breach is of utmost importance. It serves as the primary line of defense. Currently, credential gathering and leaks are widespread in the market. By implementing an MFA solution like Duo Security, we can effectively prevent these issues. When we put a stop to credential harvesting, it becomes much harder for attackers to infiltrate and navigate our network. Therefore, Duo Security acts as an excellent first line of defense. User authentication and device verification are the methods through which we envision our customers navigating in order to prevent identity-based attacks. Initially, when we employ Duo Security, it is a straightforward implementation of multi-factor authentication. As we progress, we enhance security measures by incorporating device risk assessment and potentially even regional assessment. This includes considerations such as whether the login is being attempted from a specific IP address. These gradual enhancements contribute to the establishment of an additional layer of protection. Thus, it is not necessary to implement a completely disruptive strategy right from the start. Instead, it is possible to gradually adopt and integrate this approach, following a crawl, walk, or run methodology. The Duo Security self-service portal helps free up our customers' IT staff time, allowing them to focus on other projects. As a Cisco partner, we have received feedback from our customers that the portal is highly interactive, enabling them to easily navigate and resolve issues. After setting up their Duo environment, we rarely receive callbacks for assistance, as the portal is intuitive and empowers users to handle everything they need on their own. The appealing aspect of Duo Security is its ability to establish trust for every access request, regardless of its origin. It is a cloud-based solution with excellent API integrations. It doesn't matter where or how a user logs in; Duo will be there to protect the user, whether it's through MFA, risk assessment, or similar methods. It is extremely beneficial to our customers that Duo Security considers all resources as external. Our customers frequently inquire about a zero-trust model, and this is a key component of it. Unfortunately, I would love to say that there is a simple solution for zero trust where we can just deploy this solution and be done with it. But that's not the case. It requires a layered approach, and that's what we convey to our customers. Duo Security is definitely a part of that. Duo Security has helped improve our customers' cybersecurity resilience. Internally, it protects our users from accessing sales operations-based environments. Additionally, our customers use it regularly to protect business-critical applications.

Cloud-based platform simplifies device and data center management
I find it to be good. The solution is cloud-based with the latest inspection engines, which I find to be amazing. We are less dependent on data centers and device management, which reduces our efforts significantly. It improves our device management, data center management, and updating devices. We need fewer engineers for this management, and it reduces time and efforts for data center management, device upgrades, and IT support.

Quotes from Members

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

Pros

"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."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"The console is cloud-based, which is something I really appreciate."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"Our primary use case for this product is DLP,"
"iboss has significantly lowered the number of security incidents. It is crazy how much it blocks and how much it is aware of the outside danger."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"We get fewer threats to remediate due to the two-factor authentication, which does not allow as many threats through."
"It has continuously evolved by introducing new solutions and products to address emerging security threats in our industry, demonstrating its commitment to staying ahead of evolving security challenges."
"Duo Security gives us an additional layer of security that would give us added confidence that our network will be less likely to get hacked, compromised, or otherwise."
"Duo Security improved my organization by helping us secure all access points within the company infrastructure."
"The solution is easy to use."
"My total rating for Cisco Duo is ten out of ten."
"It is really scalable. It is easy once you get an application in. You can import users from Active Directory and enroll users really fast."
"Cisco Secure solutions are great for detecting and remediating threats across our infrastructure from end to end. The integration of Talos in SecureX is great. Everything is clear in one dashboard. You have a dashboard there, your dashboard, and now you can have one look in your dashboard and see everything. It's on one pane of glass."
"The most valuable feature is its seamless integration capabilities, streamlining the process by eliminating the need for extensive installations."
"Has a good zero trust feature."
"This secure connection allows users to connect to the Zscaler VPN and access the resources on the office network, making it a highly valuable component of our system."
"Its impressive scalability allows the combination of multiple dictionaries and using them as one engine, resulting in narrower data loss gaps."
"The in-line DLP feature is one of the most vital features"
"It is straightforward to set up."
"The most valuable features of Zscaler CASB are API integration and DLP."
"As a cloud-based service, it is very easily implemented."
 

Cons

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"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."
"File integrity monitoring would be very advantageous as an additional feature."
"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."
"The dashboards for local use could be better."
"The area I would like to see improvement in is the ability with in the reporter to navigate directly to the content the user is traversing. It is kind of there, but it's not perfect. Quite frequently, I receive links that lead me to pages with error messages."
"Duo Security could be improved with the addition of more applications."
"We had some trouble with the password reset function."
"I wouldn't mind seeing some options for remembering a device for a short period of time or a specific login, particularly for administrative engineering staff, as we may be logging in to four or five different services."
"Certain customers can not use this product because it is cloud-based."
"While two-factor authentication with mobile devices provides a high level of security, it's still not foolproof, as someone could potentially steal your phone. It would be beneficial to have information about the authentication location."
"We were considering purchasing other products, like AMP for Endpoints, and it was not properly integrated with the firewall function. It might be better now with SecureX."
"Duo Security should better organize its tile feature to organize applications better."
"The product price needs improvement."
"Zscaler CASB should include integrations with other SaaS applications."
"There is some issue while accessing the portal. It takes too long."
"To enhance their offering, it is advisable for them to focus on strengthening the foundation of their architecture. Additionally, they should consider integrating a broader range of services that go beyond what managed service providers typically offer independently."
"Conflicts arise if you do not have the same management teams on the product."
"There could be a feature to view the VPN tunnel activities in terms of configuration."
"Having a Zscaler-specific device could streamline this process and provide a more consistent user experience across diverse branches."
"SCMP support would be one of the biggest improvements in my opinion. More speed improvements are also required."
"The customers would benefit from more robust documentation and conversations around configurations, as it is slightly complex."
 

Pricing and Cost Advice

"The overall pricing for iboss is very competitive and transparent."
"It is probably in line with other solutions, but I do not deal with the financial side."
"It is expensive compared to one of its competitors."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"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."
"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."
"Its price is reasonable. It is not highly expensive."
"It has a fair pricing model. I know they have different tiers, but it would be nice to have different types of licenses for certain groups of users in our organization. That way, we wouldn't have to lump everybody into one group. That would be also one complaint."
"Their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. There are no additional costs to the standard licensing costs."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"I rate the product pricing a seven out of ten."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"You pay per user when using this solution and the pricing is fair."
"The solution has increased prices this year."
"Zscaler Cloud DLP is moderately priced. We pay around 2 million rupees per year."
"The technical support is good."
"My company is a Zscaler Private Access partner, so the customers pay for the license fees."
"The product is a bit expensive."
"Zscaler SASE software is quite expensive compared to other solutions"
"The pricing is quite high, especially when it comes to the gateway."
"It has been relatively reasonable for what it does. Some of the additional license costs based on the advanced next-generation firewall functions are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. Overall, the cost seems reasonable."
