Here is some of the old landing mat primary barrier, now being replaced. It is generally 8-10 feet tall. Dirt and trash were dumped at its base in many spots, to form ramps.

Here is the existing secondary barrier - 15 foot chain link, covered with mesh, and topped with concertina. Holes can be cut with special power tools in as little as one minute.

Instead of landing mat, this will be the new primary barrier (18 foot bollard with anti-climb plate):

The new secondary barrier will be like these 30 foot bollards. Falling from 30 feet is fatal to more than half of those who fall. Just after these bollards were installed in Calexico, CA, a climber fell - breaking both femurs and his back. His life was saved by fast response, because it was under camera surveillance. Both the President and the DHS Secretary have alluded that it includes "unseen features" - some have speculated it is electrified near the top.

Bug zapper?

Now just grease the poles to make them harder to climb.

The Romans built ramps to get to the top of Masada.
