Information security and compliance
As a company working with information, GMS is well aware of the threats to information security, and we are committed to providing the best kind of data protection and security to our partners. With phishing, fraud, ransomware, data breaches and leaks crowding the headlines, information security is paramount. Being methodical, disciplined and alert in all business operations at all levels, staying up to date with the latest encryption and protection protocols, upholding the highest standards of transparency and security – all these efforts are mandatory for telecommunications companies today. More importantly, none of these measures done once guarantee protection, because even the most secure system will become vulnerable again unless it is constantly updated. Security is not a state, it is a process, requiring a responsible attitude and daily work. At GMS, we realize the risks and put the security of our partners’ information at the top of our list of priorities.
We do not tolerate negligence when it comes to cybersecurity and stand up to the challenge of keeping our partners’ data safe. A testament to our commitment to the global standards of quality, transparency, and security is GMS’ compliance with the industry’s highest standards for security procedures and all other business operations. Organizing and systematically maintaining all levels of our operations to consistently, year after year, pass the ISO certification process is an effort and expense that we do not neglect because the security of our partners’ data is of utmost importance to GMS. ISO/IEC 27001 and ISO 9001 testify to our commitment to security and compliance. Having an impeccable compliance history, we are the perfect partner for operators looking to work with only those suppliers who can abide by the highest security and compliance standards and guarantee data protection.
