You're right to question the wording. The phrase "help cybercriminals to move laterally across your network" suggests that network controls would assist attackers, which is the opposite of the intended meaning.
A clearer and more accurate way to phrase it would be:
"Networks represent the means to access our data. Using network access controls and monitoring user and device behavior in real time can provide insights and visibility into threats and help prevent cybercriminals from moving laterally across your network. Network segmentation, using threat detection and prevention tools, and encrypting network traffic will reduce the likelihood of an attack and mitigate the fallout from a breach."
This revision correctly conveys that these security measures help stop attackers rather than aiding them.
