Featured Reviews

Jack Poon - PeerSpot reviewer
Offers ease of setup and good documentation
When it comes to the product's deployment phase, we have a lot of vendor support. We have a lot of skills here in Hong Kong. Our company doesn't find any problem deploying Cisco solutions. The solution is deployed on an on-premises version. Speaking about the time required to deploy the solution, I would say that we have quite a lot of previous experience with deploying Cisco products. We have our company's standard design document, which we need to follow. We have a standard testing procedure for all those features. We just take out some appropriate parts and then compile them into one document for an individual project. It is actually quite easy for us to do the documentation, so it just takes one or two hours, and we can do the implementation because all the materials and testing procedures are already in our company standard documents, so it is not that difficult for us.

Enhanced threat detection through superior sandboxing capabilities with competitive pricing
With Trend Micro Deep Discovery, our enterprise clients can identify forgotten or unmanaged network segments, thereby mitigating unexpected network actions such as outdated antivirus software operations. When under attack, such as with ransomware, it allows us to identify the attack vector and disable it. It also assists in security audits required to prove certain network security measures.

Quotes from Members

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

Pros

"The solution can be integrated with some network electors like Cisco Stealthwatch, Cisco ISE, and Active Directory to provide the client with authentication certificates."
"I like most of Cisco's features, like malware detection and URL filtering."
"The product is inexpensive compared to leading brands such as Palo Alto or Fortinet."
"The most valuable feature is the visibility that we have across the virtual environment."
"The most valuable feature of this solution is the filtering."
"In general, the features are all great. However, if I need to take hardware for ASA, because they need to upgrade to Firepower, we want to create rules. For that, most of the time we go to the command line. Right now Firepower is working really hard on the grid. You can apply all those rules to the grid. Even if you want to monitor the logs, for example, the activity will tell you which particular user has been blocked because of that rule. Firepower's monitoring interface is very good, because you can see each and every piece. ASA also had it, but there you needed to type the command and be under the server to see all that stuff. In Firepower you have the possibility to go directly to the firewall. The way the monitoring is displayed is also very nice. The feature I appreciate most in Firepower is actually the grid. The grid has worked very well."
"Cisco technical support is unbeatable. It offers a premium service every time."
"It is quite an intelligent product."
"There is no downtime or server vulnerability with this solution."
"The most valuable features are monitoring for advanced persistent threats, the system runs in a sandbox allowing for effective zero-day exploits management, and the Inspector has a built-in sandbox."
"One of the most valuable features is the performance, since, so far, we have not faced any issues with Deep Discovery."
"The platform provides all essential features for discovery and administration."
"The most valuable feature is that the user can customize images of virtual machines in the sandbox functionality. The other vendors only use images that were created by the vendor but not the customer, end-user or partner. This helps to detect advanced threats and attacks."
"Deep Discovery is scalable and compatible with other products. It's crucial to have that compatibility because it's an integral part of our security solution. It integrates smoothly. The interface is user-friendly, so administration is simple."
"The product's initial setup phase was not difficult."
"I like the sales operations testing. and support."
 

Cons

"There are problems setting up VPNs for some regions."
"I don't think this solution is a time-based control system, because one cannot filter traffic based on time."
"The customization of the rules can be simplified."
"To be frank, the product is not really stable, although they're working on that. Whenever I go to the technical community with an issue, they will usually say that it is not there yet, but the technical team are working on it. The issues are not insolvable. I think they should just keep working on the product to make sure that the product can become very stable. The technical support is great. I appreciate that. We have a lot of communities supporting Firepower now, so you can find help for whatever issue you have."
"With the next release, I would like to see some PBR, so that you can do the configuration with the features."
"If the price is brought down then everybody will be happy."
"We are unhappy with technical support for this solution, and it is not as professional as what we typically expect from Cisco."
"I would like to have analytics included in the suite."
"Trend Micro Deep Discovery's technical support could be improved, and it could be made more active."
"The solution could be more stable and offer more security."
"I would like to see integration with third-party tools to improve the visibility of the dashboards."
"I would like to see them create a rule where It could integrate with the network and start mitigating with auto-detection."
"Trend Micro can improve the pricing in general. There is nothing else they can add or improve in the solution."
"The product's security features need enhancement."
"The solution could be more secure."
"Deep Discovery is easy to manage, but there is still room for improvement on the administration and operations side. Competing products have a cleaner interface that makes it easier to manage their products. Trend Micro offers a lot of features in one product suite, but it can be unwieldy for the customer to manage all that with a single interface."
 

Pricing and Cost Advice

"I don't know the exact amount, but most of the time when I go to a company with a proposition, they will say, "This thing that you are selling is good, but it's expensive. Why don't you propose something like FortiGate, Check Point, or Palo Alto?" Cisco device are expensive compared to other devices."
"We have a three-year license for this solution."
"Licensing for this solution is paid on a yearly basis."
"The cost is per port and can be expensive but it does include training and support for three years."
"If one is an extremely expensive product, and ten is cheap, I rate the tool's price as a five."
"The licensing cost is a bit pricey. We pay a yearly subscription."
"The tool's licensing costs are yearly. There are no additional costs associated with the product."
"Overall, Trend Micro Deep Discovery has proven to be a reliable solution that enhances our security posture while minimizing operational disruptions."
"The pricing is okay for some, and sometimes, some people find it expensive."
"The price of the solution is lower compared to the competition."
"Its price is fine, but Trend Micro can improve the pricing in general. It is a hardware solution. It is based on the number of nodes, and according to the number of nodes, clients decide which box they should acquire. They have to renew their license every year. It is subscription-based."
"The tool’s licensing costs depend on the customers."
"Overall, the price is good."
