Network Feels Slower cover — an honest accounting of milliseconds. If your Mac’s network feels slower after installing AgenShield — pages loading sluggishly, remote desktop or screen sharing lagging, file transfers dragging — this page helps you tell the two apart, because they have very different causes and very different fixes.

​
What AgenShield adds, and what it does not

The network extension inspects each new connection to apply your organization’s policy. That check costs a few milliseconds per connection. It does not sit in the path of the data itself. Once a connection is allowed, the traffic on it is handled by the operating system directly, so AgenShield adds nothing per packet and nothing to sustained transfer speed. That distinction is the whole diagnosis: A laggy remote-desktop session is the most common report, and it is almost never AgenShield. A session opens a handful of connections and then streams; a few milliseconds paid once at setup cannot produce lag you feel minutes in.

Confirm it in about two minutes

1

Measure the round trip to the machine you are connecting to

In Terminal, replacing the address with the other machine’s:
Look at the summary line. On a local network this should be a small number of milliseconds with little variation. Tens of milliseconds, or a large standard deviation, means the network path itself is unstable.This is the key test because ping does not go through connection filtering at all. If ping is slow or erratic, the problem is the network, not AgenShield — and no change to AgenShield will improve it.
2

Check your Wi-Fi link quality

A weak signal, a narrow or crowded channel, or a low transmit rate all produce exactly the lag described above. Check this on both machines — when two computers on Wi-Fi talk to each other, every packet crosses the air twice, so the weaker of the two links governs the experience.
3

Try a wired connection

Connect either machine to the network by cable and repeat the activity that felt slow. If it improves, the cause was Wi-Fi. This single test resolves the large majority of reports.

​
Other endpoint-security products on the same Mac

Most organizations run more than one security product, and each one that inspects network connections adds its own per-connection check. The effects add up, and no single vendor’s dashboard shows you the total. If your Mac runs other endpoint-security software alongside AgenShield, factor that in before attributing a slowdown to any one product. Your IT team can see the full list of installed security extensions.

When to escalate

Contact support if, after the checks above:
  • ping to the other machine is fast and stable, but connections still feel slow to establish; or
  • the slowdown appeared immediately after an AgenShield upgrade and nothing else on the network changed; or
  • a specific application stopped working rather than merely slowing down — that is a policy question, not a performance one, and is covered by Common Issues.
Include the output of the two commands above and a diagnostic bundle. The bundle contains the connection timing AgenShield records, which lets support separate our cost from the network’s without guessing.
