The solution provides an efficient, comprehensive way to manage polices for all the applications.

We use ODM to set complex business rules. For instance, we deploy this solution for most of our banking customers because there are frequent changes in the policies and business rules. These are complex to manage for enterprise applications. ODM provides an efficient, comprehensive way to manage…

Edge protection has reduced junk traffic and now safeguards APIs with automated threat intelligence

The best feature I would say is the compliance. It satisfies enterprise audit criteria for web application profiling that is required by PCI DSS and HIPAA. Also, it aligns fully with my security compliance matrices, the OWASP Top 10 alignment, and standard core rules to defend against injection attacks, cross-site scripting, and path traversal. These are the major features. The managed rule set proves that modern security does not have to be slow or complicated. It turns threat intelligence into a utility function that I can enable with a few clicks. It has eliminated the heavy operational burden of threat research. Instead of my internal security engineers spending hours tracking new malicious IPs or writing custom regex signatures to deal with emerging exploits, Imperva automatically updates the rule set in the background.

Quotes from Members

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

Pros

"It has benefited our organization by having less coding changes. Thus, we save time and don't have to hire as many people."

"ODM's most valuable features are that it's easy to define and divide business rules, and it can handle very large numbers of transactions per second."

"We would recommend this solution."

"So far, the usability is great. It's also easy to set up."

"The business owns the rules and they're taken away from IT, so business doesn't need to ask IT to implement them, and IT doesn't need to implement them. So the business owns their decisions and their rules, and therefore, finally, they take proper ownership, and model and maintain them properly."

"Its ability to use decision tables to codify the rules and manage them better."

"It's easy to build, easy to adopt for the business. Business can change those rules. I think IBM has done a good job in re-architecting the product with Decision Center as its centralized view, where the business can make changes to the rules dynamically."

"It used to take about 30 days to close at the end of the month, but now I think it's around six or seven days."

More IBM Operational Decision Manager pros

"The managed rule set proves that modern security does not have to be slow or complicated."

"Automatic updates are the best features Imperva Managed Rules on AWS WAF offers."

"Imperva Managed Rules on AWS WAF has impacted my organization positively to a very good extent, as along with the default AWS WAF rules, Imperva Managed Rules on AWS WAF is giving more edge on layer seven security for protecting the applications at the organization, making them good-to-go rules."

"Imperva Managed Rules on AWS WAF offers continuous threat intelligence updates as the best feature, as they have a rapid response to newly discovered attack techniques and base their detection logic on real-world threat data with easy integration with AWS."

"Imperva Managed Rules on AWS WAF has positively impacted my organization by addressing trust issues my customer had regarding security configuration for their application."

Cons

"One area for improvement is master data integration. That should be more fluid. The others are hierarchical drop-down lists, and hierarchical master data."

"The only thing we have trouble with is integrating IBM ODM with the cloud. The product is on-prem, and we need to migrate the rules to the cloud. It's a hectic process."

"I would like to have integration of the user interfaces, and they are putting them together in the next version of the solution."

"The platform is good. Its footprint is a little heavy. Other than that, the product works great."

"ODM could be improved with better integration with other platforms."

"There is some promise of how decisions could take advantage of machine learning and artificial intelligence. That has been slow to develop. It is still not clear where the market will take it, but that is something that I am looking forward to down the road."

"If merging could be just like SVN, that would help. It should be a lot simpler. That's the only thing I don't like about ODM, merging from our local computer up to the Decision Server. I feel like it could be a lot easier."

"Extracting specific rules could be better. We've had to do a lot of custom work on that. The testing, we've played a little bit with it, but we have our own testing methods. If it could be as simple as we have for our custom work, that would be great."

More IBM Operational Decision Manager cons

"Sometimes the rules act as a black box with Imperva Managed Rules on AWS WAF because you cannot see the underlying rule logic or regular expressions, which can be challenging when troubleshooting false positives on complex API payloads."

"Imperva Managed Rules on AWS WAF keeps updating its rule sets, but the company could increase the number of rules on a yearly basis and incorporate more rules aligned with artificial intelligence security."

"Other issues include that the marketplace sellers do not allow me to modify individual parameters inside the vendor's compiled rule set, meaning any false positive must be handled by a custom override rule."

"Imperva Managed Rules on AWS WAF can usually have false positives sometimes, blocking legitimate traffic and struggling with complex search queries, particularly with large JSON requests and certain GraphQL requests, which makes us initially deploy the rules in monitoring mode before switching to blocking mode to ensure all our use cases are supported."

"For improvement, it would be better to have access to deeper configuration levels in Imperva Managed Rules on AWS WAF."

Pricing and Cost Advice

"We made a lifetime purchase. We purchased it by number of PVUs for our stage and product environments."

"It was not a large cost. It was a one-time cost."

"We have a client who had a three-month ROI on this tool, just in additional sales, from sort of the next best action of what product that they should offer to their clients. ROI can be very quick with this product."

"ODM's pricing could be more competitive as there are open-source business rules engines that are becoming standard."

"It is an expensive solution."

"It will definitely improve the cash flow of our clients, thereby it will improve the cash flow to us."
