Istanbul is Turkey’s commercial capital and a major international business hub connecting Europe and Asia. It hosts the headquarters of hundreds of international companies and receives millions of business visitors annually.

The security picture is genuinely mixed. Crime levels are moderate compared to other P1 cities. Police are present and reasonably responsive. But the terrorism threat is real, multi-source, and has produced attacks in recent years. Add an active seismic environment and a political climate that creates legal risk for careless behaviour, and Istanbul requires a more careful risk assessment than its general reputation might suggest.

The terrorism picture

What makes Istanbul’s terrorism picture unusual is the diversity of threat actors. This is not a single-group threat. PKK-affiliated groups, IS-linked cells, and left-wing extremists have all conducted attacks in the city in the past decade. The Istiklal Avenue explosion in November 2022 (6 dead) and the cluster of attacks in 2024 demonstrate the threat is current, not historical.

The implication for corporate travellers is that general counter-terrorism awareness applies across a broader range of venue types than in cities with single-group threats. A risk assessment for Istanbul evaluates your specific hotel, meeting locations, and transit routes against the full threat landscape rather than targeting a single group’s known methodology.

The seismic factor

The April 2025 Sea of Marmara earthquake served as a reminder that Istanbul’s earthquake risk is not hypothetical. A major seismic event would have catastrophic consequences for parts of the city. Emergency response planning for a corporate visit should include building evacuation routes and, where possible, accommodation in post-1999 construction.

Our assessments flag seismic risk for specific venues where data is available and include basic emergency protocols for seismic events. A risk assessment is the first step. See our Istanbul city security briefing for the operating picture, and our executive protection service for deployment options.

Scope

Assessment Components

Multi-Group Terrorism

FCDO rates terrorism in Istanbul as 'likely'. Multiple groups maintain intent and capability: PKK/Kurdish groups, Daesh (IS), DHKP/C (far-left), and others. Attacks since 2022 include the Istiklal Avenue explosion (November 2022, 6 dead, 81 injured), a courthouse attack (2024), a church attack (2024), and an aerospace facility attack (2024). No single threat actor. The threat environment is fragmented and persistent.

Geophysical Risk: Earthquake

A 6.2 magnitude earthquake struck the Sea of Marmara in April 2025. Istanbul sits on the North Anatolian Fault and is considered at high risk of a major earthquake. Building standards vary widely. Seismic risk is a genuine operational consideration for accommodation choice and emergency planning.

Soft Target Selection

Istanbul's terrorism threat concentrates on transport hubs (airports, metro), tourist-dense areas (Istiklal Avenue, Taksim, Sultanahmet), places of worship, and venues associated with foreign interests. A security assessment identifies whether your meeting venues, hotel, or planned movements intersect with established target typologies.

Petty Crime and Scams

Pickpocketing concentrates around Istiklal Avenue, Sultanahmet, and the Grand Bazaar. Drink spiking in nightlife areas (Beyoglu) is documented. Scam bars in tourist areas have overcharged foreign nationals by significant margins. These are lower-severity risks than terrorism but affect a higher proportion of visitors.

Civil Unrest

Protests occur periodically around Taksim Square, particularly related to Kurdish political issues and political opposition movements. Police response is forceful. State of emergency powers allow rapid crackdowns. Lese-majeste equivalent restrictions on political speech create legal risk for careless public statements.

Legal and Cultural Risk

Turkey's expanded security legislation creates risk for foreign nationals. Social media posts perceived as critical of the government, its allies, or the Turkish military can lead to arrest. This is not theoretical. British and other Western nationals have been detained. Understand what you publish before and during any visit.

FAQ

Frequently Asked Questions

Istanbul has a functioning, active business environment. The terrorism risk is real but the city maintains heavy security at transport hubs and tourist areas. Most corporate visits proceed without incident. The risk assessment covers whether your specific itinerary intersects with known risk areas and provides countermeasures.

Accommodation choice matters. Modern buildings in Istanbul built to post-1999 seismic codes carry lower risk. Older buildings in the historic districts may not. An assessment includes building stock assessment for your hotel and meeting venues where seismic data is available.

For most corporate travellers, close protection is not required for standard business visits to Istanbul. Security awareness training and a vetted driver are often adequate. High-profile executives, journalists covering sensitive topics, or individuals with specific threat profiles may warrant dedicated CPO cover.
