ROI

Sentiment score

6.1

1Kosmos BlockID boosts ROI by enhancing productivity, reducing IT workload, and cutting onboarding times, leading to significant cost savings.

Sentiment score

6.0

Cisco Duo delivers high ROI by streamlining logins, lowering cybersecurity costs, and enhancing security with robust MFA features.

Initially, ten people were in the IT support team, but with the reduced ticket volume from 300 to 500 to just 70 to 80 calls monthly, only two IT staff members are now required.

Csr Kumar

Accounts Receivable Manager at Guru Nanda

Time has certainly been saved and user experience has increased multiple times over, which I consider equivalent to an ROI.

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.

Not having MFA means you cannot put a price tag on that because you will be hit with ransomware immediately.

Passwordless login has transformed daily accounting work and now saves hours on support calls

The cloud-based feature of 1Kosmos BlockID stands out because when working on SAP, it often went down due to memory size, but since 1Kosmos BlockID is cloud-based, downtime is not experienced. The second standout feature is the login ID and password recognition; it allows the right person to log in without manual entry of usernames and passwords, making 1Kosmos BlockID very helpful in any situation. 1Kosmos BlockID offers passwordless authentication that eliminates 2FA. It operates through biometric authentications, such as facial recognition and thumb impressions, which are compliant security keys for enterprise applications. Identity verification is another strong feature; if 1Kosmos BlockID recognizes a user, it ensures that the right person is logging in. It uses AI and machine learning to scan government-issued IDs, licenses, and passports, matching them with user biometrics for 100% accuracy. The digital wallet feature also stores user identity information in a private or permissioned blockchain, allowing users to control their personal data. It meets high assurance standards, including NIST 800-63-3 and GDPR, and supports both app-based and browser-based user journeys for onboarding and authentication. 1Kosmos BlockID has positively impacted the organization by enhancing security through eliminating usernames and passwords and storing encrypted user data in a private permissioned blockchain, which drastically reduces the risk of data breaches and phishing. Furthermore, it has improved operational efficiency by streamlining the user experience, reducing help desk calls for password resets and simplifying identity management, thus increasing overall productivity. In terms of time savings, for a team of 15 people, a monthly saving of around eight to ten hours has been observed after using 1Kosmos BlockID. Before its implementation, the IT help desk faced 300 to 500 calls a month. After using 1Kosmos BlockID, that number reduced to just 70 to 80 calls monthly, significantly alleviating common password-related issues.

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.
