As of update 25.1.3, I found the following method consistent to spawn a Denial Bursa.

Go to Laomedeia in Neptune and do Spy. You don't have to complete all vault, just enough to complete the mission. Right before extraction, find a room with control console. Move away a bit from the console and start killing (if you use invisible frame like Loki, you need to be visible from now). Don't kill too fast, and make sure to give enemies a chance to raise alarm. Keep kill enemies until they raise alarm again to trigger lockdown. At the point, Lotus will inform you that the alarm has attracted a reinforcement (a bursa). The bursa could be any type of Bursa, so you may need to try a few times to get all the Denial Bursas.

This method works consistently, and if you want you could run all the vaults for rare items (Ivara, Rime Rounds, etc).
