Are MI5 more detectives or spies?

I've always assumed MI5 was similar to USA's FBI and Marshalls, but after watching Spooks and Slow Horses, they seem more like James Bond at home?

And if they are more spooky, are there other agencies that fill in the national-level investigation and law enforcement pieces of the puzzle?
