Security at Nmbrs

Safe HR and Payroll software is both our profession and guarantee. The security of our platform, network and products are our highest priority day and night.

We safeguard your privacy

Nmbrs will never use the data for purposes other than HR- and payroll related practice, and we are determined to make sure nobody else ever will. All customer data that requires storage is located in the Equinix datacenter with the highest levels of security and operational reliability. When data-sharing occurs with applications or tools that enhance our product, this happens in compliance with the EU Data Protection Act. That means that the shared information is very limited and does not expose any kind of personal sensitive data.  







The new General Data Protection Regulation (GDPR) went live on May 25th, 2018. Obviously, this has implications for Nmbrs and its services. Since the 1st of February, we have employed a compliance and risk officer, who is dedicated to rolling out this project. Of course, the compliance officer is registered at the Dutch Data Protection Authority and will make sure to inform all those involved as accurately as possible.

How do we secure your data?

We have taken measures to make Nmbrs both secure and convenient for our partners and users. We use several tools for application, infrastructure and user monitoring that alert our operations team to act in critical situations. For the complete picture, the Nmbrs IT whitepaper offers an elaborate explanation of the efforts and policies that help secure our data.



Data traffic to our servers is controlled 24/7 from a central control room. Within 30 minutes, Nmbrs will respond to unauthorized attempts to access to the web service, irregular traffic or other attempts to subvert Nmbrs. The Nmbrs infrastructure is protected by a Firewall managed by hosting partners that continuously identify potential threats. Each server that is accessible from the Internet (web-servers) is also protected by an extra Operating System Firewall. 

SSL Encryption

The client/Server communication is done with HTTPS, which guarantees data integrity and prevents data tampering. The Nmbrs certificate uses a 2048 bit encryption. The HTTPS transport layers uses a standard TLS without fallback to SSLv2/SSlv3, which are disabled because of security reasons. Internet users are able to recognize the SSL-secured status by the lock icon before the website URL, and Extended Validation SSL-secured websites by the green address bar.

User Authentication

Nmbrs offers a range of policies for password requirements, including options for periodical password resets and pin codes. Furthermore, Two-factor authentication provides an optional second authentication level. Nmbrs does not store user's passwords itself in the database, but instead, a salted hash of the password. This prevents password stealing even with database access.

IP Validation

Every user has a whitelist with approved IP addresses to access the system. When users access the system from a new IP address an email is sent to verify the new IP. It is also possible to restrict access to Nmbrs to a list of IP’s or IP ranges. This measure helps to to prevent third parties from entering Nmbrs accounts from alien locations and devices.
