Customer security is enhanced with software and update detection while licensing process needs improvement

A quick specific example of how I use Field Effect MDR to keep my customers secure is that it helps me identify computers that need updates, even when I believe they are already updated. Field Effect MDR finds software and Windows updates that aren't being completed, which I find very valuable.

Quotes from Members

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

Pros

"The most valuable features are AROs, which provide timely notifications for out-of-compliance or out-of-specification detections."

"I like how comprehensive Field Effect Covalence is."

"One of the most useful and impressive features of the system is its detailed notification mechanism."

"It is very user-friendly. We have regular reports to see what is going on."

"What I like the most about Field Effect Covalence is the ease of deployment, the fact that it's cost-effective to roll out, and it is reasonable."

"The most valuable features are Action Recommendations of Observations, which keep us informed about existing vulnerabilities so we can proactively update our endpoints and those of our customers against potential threats."

"The automated response feature is incredibly effective."

"Hackers are trying to breach a business when they least expect it - that's often at night, weekends, and holidays. Covalence never sleeps or misses a second of monitoring."

More Field Effect MDR pros

"ReliaQuest GreyMatter has helped us to reduce security incidents by 89%, which is a significant amount of incidents we have seen."

"ReliaQuest GreyMatter saves around 60% of time or resources."

Cons

"The tagging of ARO closure has room for improvement."

"In my experience, Field Effect MDR is somewhat stable. However, I have one situation where it has been two months trying to resolve an installation issue on a server, which has consumed a significant amount of time."

"Covalence's SEAS feature wasn't very user-friendly."

"It would be more effective if it could surgically isolate the specific malicious process instead of deleting the entire machine."

"While it's essential to stay informed about potential issues, the recurring notifications about past vulnerabilities can lead to confusion and may detract from our focus on current threats."

"In terms of improvement, there are instances where the ARO responses are slightly slower than preferred."

"I'd like improved visibility into the backend data where logs are stored, along with integrations with a wider range of products."

"Some resources lack experience, but issues can be escalated to more knowledgeable contacts."

More Field Effect MDR cons

"Areas that have room for improvement include user interface and integration."

Pricing and Cost Advice

"Although Covalence is expensive, it provides good value for the price."

"A top-tier competitor to Field Effect in Magic Quadrant that we had been using until our switch to Field Effect was a great product, but each capability had an additional charge. We had to license modules separately, and each of those add-ons had to be added onto its own consumption and agreement. It was a nightmare from a billing perspective because we had multiple agreements, and each one had a jagged anniversary or a renewal anniversary. It was a nightmare, whereas Field Effect MDR is one product."

"It is on the high end, but it is worth it for the service that you get from them."

"Field Effect is fairly priced from my perspective. You get a lot of bang for the buck with this and a level of visibility that provides you with greater peace of mind knowing that the system is carefully monitored. You also have automated responses for known malicious behavior at any time of the day. Someone could have their Office 365 mailbox compromised at 2 in the morning on a Saturday when most people are asleep or not paying attention, and the system can prevent an issue in an automated way."

"The pricing is fair and reasonable."

"The licensing model itself is solid, but we're ironing out some inconsistencies in how customer profiles are configured."

"We were particularly impressed with their pricing model, which charges per user rather than per system."

"While the contract duration might change, the pricing remains highly attractive."
