A security troll patrolling the North Wing after Sirius Black attempted to enter the Gryffindor Tower

"A bunch of surly security trolls had been hired to guard her. They paced the corridor in a menacing group, talking in grunts and comparing the size of their clubs."
—Security trolls guarding the Fat Lady[src]

A security troll was a specially-trained troll who guarded certain places and objects in wizarding society.[1] Some wizards and witches made their living out of training security trolls.[2]

History

1993-1994

In 1993, Albus Dumbledore hired security trolls to guard the Fat Lady's portrait after Sirius Black attacked her in an attempt to get into Gryffindor Tower and Sir Cadogan was fired for letting him in while he was covering for the Fat Lady. These Trolls were placed in the North Wing and were evidently a different type of Troll than the mountain variety, since they seemed considerably more intelligent and less smelly. They spent all their time pacing the corridor in front of the Fat Lady's portrait, giving dirty looks to everyone who happened by and comparing the sizes of their clubs.[1] They left at the end of the year, when Sirius led the Ministry into knowing that he fled out of the country.

1996

In 1996, Dolores Umbridge apparently hired an armed security troll to guard Harry Potter's Firebolt.[3] This was after Fred and George Weasley made their final departure from Hogwarts and had stolen their brooms back, Umbridge decided that it would be best to move Harry's broom to the Dungeons with the added security measure of security trolls.[4] It was eventually dismissed when Umbridge left, and Harry got his Firebolt back.

Security trolls were employed at Gringotts Wizarding Bank, helping to inspect lifts and carts.[5]

In the 21st century, security trolls were unleashed as a Confoundable by the Calamity and had to be dealt with by the Statute of Secrecy Task Force.[6]
