Sorry, my phrasing was a bit off, I know that the master server pushes all the rules to its endpoints, provides admins a overview and statistics and so forth (basically the same way as Sophos does for their Endpoint Protection except that Sophos doesn't really include any noteworthy features in their EP, except AV, since most of it should get dealt with by the UTM).
My question was more like: Is there any engine/protection/performance difference between the managed and un-managed version? I couldn't find any information in that regard, so I assume it's basically equal.
Yes there is a performance difference also in terms of protection. While the engines are the same the standalone version uses a bit more resources as the whole rule/policy-set is being loaded and 24/7 active hence a bigger memory and CPU footprint, in regards to the protection the standalone version is great yet its a mere shadow compared to the managed version.
The managed version pushes the rule/policy set over the network on a case by case situation.
Which means that if there is no traffic or no processes running that require SEP to monitor then all the clients become IDLE.
The un-managed version has its rule/policy set permanently loaded and as such is far more active then SEPM.
And this is simple to explain, on a big company network having SEPM run 24/7 in full active mode would make the load upon the network and its parent applications and processes bog down the system, as you are talking in some cases about hundreds if not thousands of connected end points so you understand that having them all in full swing even while their host system is idle will produce a significant load on the network.
Which degrades performance.
Hence why SEPM only comes into action when there is a request by a protocol or a process that requests monitoring based upon trigger rules.
The standalone version does not have that trigger system, since there is no need for it and it basically runs like your average Internet security package.
Does this answer your question?
Kind Regards Nico
