“Security solutions are numerous, but why can't threats still be stopped?” “Tools are overflowing but not interconnected, Warnings are pouring in, but aren't you missing what's truly important?” Now is the era when not just simple defense, but proactive and active 'action-oriented security' is needed. At its core is Microsoft's unified security. From ID, devices, apps, cloud, to infrastructure, connecting all security elements into one, AI detects, assesses, and eliminates threats in real time. Microsoft Security is not just a 'defense solution' but a real-time response system that protects the entire enterprise. Now, don't regret it after an incident occurs. Start security 'in advance', 'proactively', and 'smartly' with the Microsoft unified security platform, starting today.
