United States Department of Homeland Security

"You know, when they first started Homeland, they wanted native speakers. Farsi, Pashtun, Arabic. Use the enemy to catch the enemy."

- Dinah Madani to Sam Stein

The United States Department of Homeland Security, occasionally referred as Homeland Security or DHS, is a department of the United States government that deals with threats to the public security in the country.

Kandahar Case
Homeland Security Liaison Dinah Madani was sent to Kandahar, Afghanistan where he served alongside with local Afghani policeman Ahmad Zubair. Together they investigated criminal activity in the Kandahar until Zubair was captured and killed by group of soldiers. Madani received a recording of Zubair's murder from unknown source, but evidence was stolen while she was in Kandahar.

Attack on David Lieberman
When William Rawlins had learned that hacker named Micro has been sent a video footage of a execution of Zubair, he learned his identity and sent senior Homeland agent Carson Wolf and group of agents to him. After high-speed chase, Wolf shot him in the chest but Lieberman survived.

Just as New York Bulletin editor Mitchell Ellison once had someone ready to run a story about Micro, he was then personally visited by Wolf not to publish the article, under the guise that it would compromise their investigation.

Chase of Lincoln Campbell
Homeland Security was one of the agencies that tried to track down and capture inhuman Lincoln Campbell.

"FBI, Homeland Security. Whatever it is you stumbled onto last night, it's big."

- Jeri Hogarth to Jessica Jones

Alongside with NYPD and FBI, Homeland Security investigated mystery criminal activities in New York City.

Returning Home
Agent Madani was transferred from Kandahar to the DHS New York Office. While in New York City she was made partners with Sam Stein, a junior agent under the direct orders of Carson Wolf. She told him about Zubair's death and her investigation. Also, Dinah asks Sam to get her all the information they have on Colonel Ray Schoonover and Lieutenant Frank Castle. She was sure that Schoonover and Castle are in the footage that Madani losed, but since they are (to her knowledge) dead, she wants to talk to Billy Russo who served with Castle in Afghanistan.

Training with Anvil
Madani and Stein with group of DHS agents go through the tactical exercise with Anvil, private military company, owned by Russo. While conducting a training, Russo personally greeted Stein who was disappointed in his own performance during the simulation as he had come close to shooting a hostage.

While Stein left to return the equipment, Russo then introduced himself to Madani who questioned if Russo was the man in charge of the operation there, which he confirmed. He suggested that Anvil could make a deal with Homeland Security as a contract would be good business for them.

Attack on Carson Wolf
Stein and Madani started investigation of Carson Wolf's death. Operation Director Rafael Hernandez promoted Dinah to senior agent. Sam gives her evidence that Wolf had $30 million in off-shore bank accounts. Dinah asks Sam to sit on the information as she doesn't trust anyone.
