What do you like best about Telesign Verification?

I like the API Integration that you can establish with this product as it allows you to connect it with othe tools that you can schedule when sending messages and engaging your customers. If we need to make a follow up, we can schedule a message and set reminders and we do not need to do it manually one by one. Also, it prevents us from taking time on fake accounts and we can verify it right away. Security is a big thing and we are able to stop fraudster Review collected by and hosted on G2.com.

What do you dislike about Telesign Verification?

Pricing. I believe if there are some customizable solutions that they can offer based on the need and provide more package solutions, that would be great Review collected by and hosted on G2.com.

What problems is Telesign Verification solving and how is that benefiting you?

The main area that this tool is very useful is Fraud Prevention and Security Solutions. This allows us to filter our focus on those numbers that are authetic rather than having to target on those non profitable prospects which are fraudsters in the first place Review collected by and hosted on G2.com.

What do you like best about Telesign Verification?

The most helpful part of Telesign verification is its multifactor authentication (MFA) capabilities. It enhances security by combining multiple verification methods, such as SMS, voice calls, and app-based authentication. This multi-layered approach reduces the risk of unauthorized access and helps ensure that only legitimate users can complete the verification process. Review collected by and hosted on G2.com.

What do you dislike about Telesign Verification?

One of the least helpful aspects of Telesign verification could be its reliance on phone-based methods like SMS and voice calls, which might be less effective in cases where users have poor network coverage, experience delays, or have limited access to mobile services. Additionally, if users are in regions where these methods are less reliable or where they prefer alternative forms of verification, it might impact the overall user experience. Review collected by and hosted on G2.com.

What problems is Telesign Verification solving and how is that benefiting you?

It helps prevent fraudulent access by ensuring that users are who they claim to be through multi-factor authentication methods. Review collected by and hosted on G2.com.

What do you like best about Telesign Verification?

As a developer, I was really happy to see the detailed documentation on Telesign's developer website. Implementing OTP auth is one of the most challenging and time consuming tasks and this makes it really easy to implement so that I can focus on my proof of concept.

What do you like best about Telesign Verification?

I liked the fact that it is easy to implement and provides MFA, too. Authentication is handled automatically so less technical debt and less handling of auth. everything is done automatically. Review collected by and hosted on G2.com.

What do you dislike about Telesign Verification?

It is still dependent on username, password, and phone number. There are other companies that are building passwordless authentication mechanisms. So, if this is also implemented, it would be amazing. Review collected by and hosted on G2.com.

What problems is Telesign Verification solving and how is that benefiting you?

It solved the problem that I do not need to manage too much authentication features as most of it is implemented already. So there is less technical debt. Review collected by and hosted on G2.com.
