Director - Network Operations & Strategy, Workonline Communications (Pty) LtdInternet has vastly grown in size over the last two decades. Although the tools nowdays exist, many providers have not taken the correct steps in order to address critical security issues. MANRS is the right way for network and cloud providers to further engage with internet security and make the internet safer for everyone. Hostmein IKE is a leading Greek cloud and data center provider providing mission critical services. Security for Hostmein is a critical aspect. MANRS actively helped us implement a better security policy for our network by setting the correct guidelines.
