On 10 November 2004, two suspected attackers were captured after an hour-long siege of a building in The Hague.
They were in possession of three grenades and were accused of planning to murder Wilders as well as a fellow MP, Ayaan Hirsi Ali.
The suspects were presumed to be members of what the Dutch intelligence agency, the General Intelligence and Security Service, has termed the Hofstad Network (Hofstadgroep).
Since this incident Wilders has been under constant security protection because of frequent threats to his life.
In September 2007, a Dutch woman was sentenced to a one-year prison term for sending more than 100 threatening emails to Wilders.
In 2009, a rapper from Rotterdam was sentenced to 80 hours community service and a two-month suspended jail term for threatening Wilders in a rap song.
Wilders was listed as the most threatened politician in the Netherlands in 2008.

Wilders is said to have been "deprived... of a personal life for his... hatred of Islam".
He is constantly accompanied by a permanent security detail of about six plainclothes police officers, and does not receive visitors unless they are cleared in advance, thoroughly searched, and escorted at all times.
He lives in a state-provided safe house which is outfitted to be bulletproof, is heavily guarded by police, and has a panic room.
He is driven from his home to his offices in parliament in an armored police vehicle, and wears a bulletproof vest.
His office is located in the most isolated corner of the Dutch Parliament building, and was chosen because potential terrorists can get to it through only one corridor, making it easier for his bodyguards to repel an attack.
He is married to Krisztina Wilders (née Marfai), a former diplomat from Hungary of Jewish origin, with whom he can only meet about once every week due to security concerns.
The restrictions on his life because of this, he said, are "a situation that I wouldn't wish on my worst enemy".

In January 2010, Karen Geurtsen, a Dutch journalist from the magazine HP-De Tijd, revealed a painful breach of security.
She spent four months working undercover, posing as an intern, for the PVV party.
She claimed that she had had unchecked access to Wilders. "
I could have killed him", were the first words of the article that she published about this operation.
According to her, she had "dozens" of opportunities to take his life.
In July 2010, after Wilders complained that his security was inadequate, the Special Security Assignments Brigade, a special unit of Dutch military police, made four attempts to smuggle a firearm into the heavily guarded offices of Wilders' Freedom Party, two of which were successful.
Following these breaches, security at the offices was increased.

In June 2011, disclosure of Wilder's personal finances indicated that he had founded a self-administered company one year earlier without reporting this via the public records of the House of Representatives, which he, as a parliamentarian, should have done.

Wilders has been dying his hair since at least the mid 1990s having previously gotten his hair cut at a barber shop near Utrecht Central Station until this was stopped due to security concerns.
As a result of aging, Wilders' dark roots no longer show up due to increased graying.
Wilders has acquired nicknames such as "Mozart" and "Captain Peroxide" because of his flamboyant platinum blond hairstyle.
Radio Netherlands calls him "the most famous bleach-blond since Marilyn Monroe".
