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clients can identify forgotten or unmanaged network segments, thereby mitigating unexpected network actions such as outdated antivirus software operations.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

"It is quite an intelligent product."

"It has a huge rate of protection. It's has a low level of positives and a huge rate of threat protection. It's easy to deploy and easy to implement. It has an incredible price rate compared to similar solutions."

"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."

"The product is inexpensive compared to leading brands such as Palo Alto or Fortinet."

"The whole solution is very good, and stable."

"It simplifies the configuration process by offering pre-defined base configurations, including security and connectivity settings."

"Cisco technical support is unbeatable. It offers a premium service every time."

More Cisco Sourcefire SNORT pros

"The most valuable feature of Trend Micro Deep Discovery is its complete end-to-end visibility of threats."

"The performance and stability are great."

"Generally speaking, it just gives us a broad understanding of exactly what kind of threats occur. The submission point, analyzing point, and virtualization are within the environment that it supports. It helped us to improve our security levels and protect our internal network from any threats outside."

"Trend Micro Deep Discovery Email Inspector includes its ability to perform mail detection and mail filtration against various email attacks such as phishing and spam, serving as an email gateway for both inbound and outbound traffic."

"Trend Micro Deep Discovery is a very specific product for threat intelligence with smart protection."

"The most valuable features are the protection and that it is fast."

"The platform provides all essential features for discovery and administration."

More Trend Micro Deep Discovery pros

Cons

"There are problems setting up VPNs for some regions."

"The pricing needs to be improved. We have lots of low-budget clients around us. Budget constraints are always a deterrent in our market."

"Performance needs improvement."

"The implementation could be a bit easier."

"We are unhappy with technical support for this solution, and it is not as professional as what we typically expect from Cisco."

"I don't think this solution is a time-based control system, because one cannot filter traffic based on time."

"I did not experience any pain points that required improvement. Maybe a couple of false-positives, but that's about it."

"The customization of the rules can be simplified."

More Cisco Sourcefire SNORT cons

"The solution needs improvement in terms of pricing."

"The product's scalability feature needs to be improved, as it is an area in the product with certain shortcomings."

"Additionally, better scanning capabilities for third-party applications would ensure comprehensive security without the need for exclusions."

"There are certain aspects of flexibility in the policies that should be added to Deep Discovery."

"The main issue is its high cost."

"The product's security features need enhancement."

"Trend Micro Deep Discovery is a very expensive solution, making it very hard to sell."

"The stability of the solution could be improved. It should be 100% stable, but it's not there right now."

Pricing and Cost Advice

"Licensing for this solution is paid on a yearly basis."

"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."

"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."

"We have a three-year license for this solution."

"The pricing is okay for some, and sometimes, some people find it expensive."

"Trend Micro Deep Discovery is quite expensive compared to other endpoint security products."

"Compared to its competitors, Trend Micro Deep Discovery is a little expensive."

"The licensing cost is a bit pricey. We pay a yearly subscription."

"The tool’s licensing costs depend on the customers."

"The price of the solution is lower compared to the competition."

"Overall, Trend Micro Deep Discovery has proven to be a reliable solution that enhances our security posture while minimizing operational disruptions."

"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."
