ROI

Sentiment score
5.9
Cisco Duo enhances security, reduces costs, and improves efficiency with multifactor authentication and simplified management, boosting ROI and satisfaction.
Sentiment score
6.2
ThreatLocker enhances security, reduces costs, boosts productivity, and facilitates growth by blocking unauthorized applications and preventing malware.
We were able to implement zero trust extremely quickly because of the platform and its ongoing developments, including Cisco Duo Network Gateway, which enabled that transition to zero trust extremely quickly.
Global Associate Director, Services at a leisure / travel company with 1,001-5,000 employees
Not having MFA means you cannot put a price tag on that because you will be hit with ransomware immediately.
Director at a tech vendor with 10,001+ employees
The biggest return on investment was the ease of use for the end users to have that secondary authentication when logging into the critical systems.
Manager, Data Center at a real estate/law firm with 11-50 employees
If something were to happen without ThreatLocker, the cost would be huge, and thus, having it is definitely worth it.
Tier 1 IT Engineer at a retailer with 11-50 employees
Based on what we use ThreatLocker Zero Trust Endpoint Protection Platform for with the same functionalities and packaging, it was around 13 or 14 hours.
Head Of Cyber Security at a outsourcing company with 201-500 employees
We have the MDR package as well, and just knowing someone is watching those endpoints at 3:00 a.m. is a lifesaver that you cannot put a dollar figure on.

Information Cybersecurity Technology Specialist at Freez.it

COO at Panda Technology
 

Room For Improvement

Cisco Duo needs better integration, competitive pricing, improved usability, enhanced device compatibility, and easier deployment to satisfy users.
Users seek improved training, integrations, transparency, UI, and communication in ThreatLocker Zero Trust Platform for enhanced usability and administration.
If you don't have internet access, you can't access your computer, only local access is available.
Security and Network Team Lead
It lacks some dynamic identity management features compared to other products such as SailPoint.
Senior Iam Associate at Cognizant
Not only has the product been very good and we have done fewer support cases, but I think support overall has been very fast.
Network Engineer at a university with 10,001+ employees
Controlling the cloud environment, not just endpoints, is crucial.
COO at Panda Technology
ThreatLocker Zero Trust Endpoint Protection Platform could improve by being a little more hands-off, perhaps by having a team inside ThreatLocker that does all the vetting of patches; having one person hired by ThreatLocker to check out patches means that a million other industries using ThreatLocker Zero Trust Endpoint Protection Platform do not have to vet the same patch, ultimately saving time and money around the world.
Technical Support Engineer at CMIT Solutions of Central Orlando
This feedback would help us understand what is learned in real-time, especially during a one-hour learning mode setup, ensuring we remain aware of potentially unnecessary learned items.
Server Administrator at Clay County Sheriff's Office
 

Setup Cost

Sr. Network Security Engineer at Topnet Internet Services Provider. Riyadh, Saudi A
After conversations with other partners, it became clear we underpriced it initially, which caused most of our issues.
Director, Managed Services at a consultancy with 11-50 employees
We are moving towards the Unified solution, where they basically bundle everything together, providing us better stability with the ability to bring in new product offerings without having to go back to the customer and say, 'This is going to cost you.'
Supervisor, Client Security at a consultancy with 11-50 employees
Money is saved because it is not costly, and I would suggest it for other companies.
Helpdesk Engineer at Computer Network Infrastructure (CNI) Consultants

Cyber Security Specialist at Bremmar Consulting
It protects our customers.

Featured Reviews

Charles Slaustas - PeerSpot reviewer
Information Technology Contractor at Insight global
Supports seamless authentication for users across multiple organizations and personal portals
The features I use in Cisco Duo include Duo Pushes to confirm my identity to the device, and eventually as MFA security was increased, I actually had to use exchange passcodes. Sometimes, I have to go into the site and get into Cisco Duo to retrieve the passcode, and many of them have been two-factor, where the sites send a passcode that I have to enter into Cisco Duo. It has been more of the latter. I have not seen issues with lagging or crashing on Cisco Duo's end; it was usually on the client end, often because someone set up a bad upgrade or there were connection issues with the Cisco Duo cloud through the administrative site.
Santo Joy - PeerSpot reviewer
Head Of Cyber Security at a outsourcing company with 201-500 employees
Security controls have been strengthened with granular application, ringfencing, and access policies
The features of ThreatLocker Zero Trust Endpoint Protection Platform that I like the most are the Ringfencing, elevation control, storage control, and application whitelisting functionality. For examples of how these features benefit my company, we were looking for a solution across various vendors to actually implement application whitelisting controls. ThreatLocker's agent, which is very lightweight and does not use much CPU or RAM, helped us achieve that solution. Ringfencing was an add-on that ticked off a lot of Australian framework security controls, which is the reason we chose it. My impression of the allowlisting feature in terms of managing which software, scripts, and libraries run on my devices is that ThreatLocker's community page has a lot of information around this, which is very helpful. Not only that, the Cyber Hero support that ThreatLocker provides gives us insights and best practices, helping us achieve that solution and guiding us to the right platform. The impact of Ringfencing on controlling the behavior of approved applications has been a big winner for us because it is something that many other platforms do not provide as a functionality. Having that allowed us to identify what applications talk to each other, which is something that many other platforms do not do. The network control feature impacts my ability to manage network traffic across my endpoints and servers. We have not used this widely across all our partners, but wherever required, we use it. It has been an easy solution for those customers to get that control implemented. The elevation feature's role in facilitating just-in-time administrative access for approved applications shows that elevation control helps in many use cases involving remote control platforms, door usage, and security system platforms that require local admins. There are many solutions that provide this functionality, but the licensing cost seems to be expensive, and it also adds another solution into the mix. Rather than doing that, we try to use ThreatLocker Zero Trust Endpoint Protection Platform to achieve that control. Regarding the storage control feature, I have used it. The primary function is USB blocking, which is very widely adopted, and also just locking down and allowing certain users to access certain file locations helps us there. When it comes to enforcing policy-driven access over various storage devices, it depends on the business risk adapted by the companies that we support, but generally the use case is USB and external storage devices where companies know that is a risk, but they do not have appropriate solutions. There are EDR platforms that claim to do this, but ThreatLocker Zero Trust Endpoint Protection Platform does it at an advanced level. My assessment of the efficiency of the real-time threat intelligence and category controls employed by Web Control in blocking malicious and non-compliant sites leads me to think that Web Control is another functionality within ThreatLocker Zero Trust Endpoint Protection Platform that is an add-on on top of the current set. That is another solution that we use based on what is required for the company, but again, that is not widely adapted yet for our partners.
