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

"It's running in the background and does a packet-level analysis of everything that comes in. It also has an auto-response feature, so if something gets through and is clicked on, or somehow gets through the network, it gets isolated and quarantined, and we get notified."
"One of the most useful and impressive features of the system is its detailed notification mechanism."
"The AROs have been incredibly helpful."
"It is easy to manage surveillance."
"It is very user-friendly. We have regular reports to see what is going on."
"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."
"The most valuable aspect of Field MDR is the comprehensive visibility the solution offers. Most solutions cover the traditional threat landscape of computers, endpoints, servers, etc. However, there are also things happening within the network environment, such as WiFi, mobile, the Internet of Things, smart TVs, video surveillance systems, etc., that have associated vulnerabilities. Most environments do not manage or protect these assets."
"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."
More Field Effect MDR pros
"ReliaQuest GreyMatter saves around 60% of time or resources."
"ReliaQuest GreyMatter has helped us to reduce security incidents by 89%, which is a significant amount of incidents we have seen."
 

Cons

"There are tags for security threats, but I only view them. I do not action anything. I just see what is happening. Sometimes, they are a little bit vague, and I am unsure what they mean, so I leave that to the IT experts. Overall, we are quite satisfied with their product and how it is working."
"Because this is a security solution, I would recommend that they extend their support hours, and perhaps for emergencies, even to 24/7 or 24/5."
"They could use more third-party integrations with other MSP tools."
"It would be incredibly valuable to have the Field Effect team handle some of the third-party application patching they're currently identifying."
"Field Effect MDR could broaden its cloud application integrations to integrate better with Office 365, Azure, Salesforce, etc. They integrate about 15 to 20 out of the box. I'd love to see a lot more than that."
"If they can include an email filter system, that would be great."
"Some resources lack experience, but issues can be escalated to more knowledgeable contacts."
"The ConnectWise PSA integration is two-way but does not send our comments back to the Field Effect portal."
More Field Effect MDR cons
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"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."
"Although Covalence is expensive, it provides good value for the price."
"The shift to a per-user pricing model and the introduction of a base price for the on-premises or virtual appliance has been particularly advantageous."
"It is a little pricey. It is a little on the high end, but we are continuing to use it. We signed the contract and have not canceled, so we find value in having it."
"The pricing is fair and reasonable."
"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."
"We're currently enrolled in the volume package, which offers tiered pricing based on usage."
"We were particularly impressed with their pricing model, which charges per user rather than per system."
