Fast, secure, hosted SFTP solutions

Maytech provides fast, flexible and secure file transfer solutions enabling you to send and receive files of any size, anywhere in the world.

Fast, because we send your files over an uncongested global network, and secure, because our services are approved and certified for use with government, medical and personal data.

Our SFTP hosting has an online management console to administer users, access usage logs and manage your files, putting you firmly in control of what’s being stored and shared by your users and systems.

SFTP hosting solution

Replacing internally managed SFTP systems

Our SFTP services often replace internal systems, removing the requirement to purchase, manage and support them with a fully managed and supported system. This reduces capital outlay, provides a high-quality service for users and reduces risk, especially at the edge of the network by opening fewer external inbound connections through your firewall.

SFTP file sharing automation

Automate file transfers over SFTP for machine to machine workflows using our reliable, secure and fast hosted service. Use .NET scripting or any other programming language to connect via a third-party application.

Send or receive sensitive documents including payroll, personally identifiable information, medical records or commercially sensitive papers automatically, without the need for manual intervention.

Enterprise software such as Oracle or Microsoft Dynamics can also be integrated to provide a seamless solution as a part of in-house infrastructure.

Retail customers such as Fatface, Ted Baker, Joules and many other fashion-sector retailers use Maytech to integrate back-office systems by exporting data and sending data securely between retail locations, back office and warehousing.

When the London Boroughs of Havering and Barking & Dagenham combined their business rates processing, Maytech, an approved government supplier, stepped in to provide a secure cloud file-sharing solution for the constant flow of data they required.

Secure API for SFTP + administration

For those users who wish to do more than simply manage files via SFTP applications, accessing our system via a secure API enables the management of users, quotas and folders, as well as any other action you would normally complete via our web interface. This includes interacting with files.

SSH secure key authentication for SFTP

Depending on your requirements, regular SFTP authentication based on usernames and passwords may be implemented through an administrative console, or SSH secure key authentication can be applied and tied to an application. Should you have any questions on how this works or what the best option is for you, our team of technical experts and client services specialists are on hand to assist you.

Restrict IP addresses

Prevent unauthorized access and lower the risk of attack by restricting user access to a specific IP address or a range of addresses.

With a couple of clicks within the Quatrix Administration, Admins are able to easily add, change, or remove IP address restrictions for the whole account. You set IP or IPs, so that users with these IP addresses only are allowed to sign in to Quatrix. Access outside the set array is denied.
