What companies need to prepare for in a changing environment
Heading into 2026, the security environment is changing rapidly.
Geopolitical tensions, technological advances, and social changes are intersecting,
making the risks faced by companies increasingly complex.
In this article, we review the key security threats
and summarize how organizations can prepare from a strategic perspective.
A more complex security environment
Today’s security environment is more complicated than ever.
Geopolitical tensions, hybrid threats, and information disorder
are interlinked and forming a single, continuous trend.
These changes show that it is no longer enough to respond to individual threats.
They highlight the need for more integrated and proactive security strategies.
01. Growing threats to Critical National Infrastructure (CNI)
Attackers are expanding their focus beyond traditional critical infrastructure
such as energy and water, to include newer areas like data centers.
We are seeing more cases where physical attacks and cyberattacks are combined,
and technologies such as drones are enabling actors to cause major impact
with relatively limited resources.
These threats can lead not only to physical damage to facilities,
but also to operational downtime, supply chain disruption, and financial loss.
Companies need to consider not only direct exposure,
but also indirect impacts through their supply chain and partners.
02. Increased security risks in public spaces and events
Public spaces and events, which are highly accessible and attract large crowds,
continue to represent major security risk areas.
As social issues and political conflicts intensify,
the likelihood of activism, insider threats, and extremist behavior is also increasing.
At the same time, easier access to online information
makes it simpler for threat actors to plan in advance.
As a result, event security now requires more than on-site response.
It calls for a comprehensive approach that includes crowd flow analysis,
local context assessment, and pre-event intelligence gathering.
03. Internal and external risks linked to corporate policy changes
Policy changes related to Environment, Social, and Governance (ESG)
can trigger new types of risk.
Backlash against a company’s strategic direction
may lead to boycotts, information leaks, and reputational damage,
and in some cases, the criticism can extend to individual executives.
In this environment,
security measures must be considered together with communication
and reputation management.
04. Threat information spreading through open sources
Online platforms and social media are accelerating the spread
of extremist content and attack-related information.
As a result, we are seeing more cases
where individuals plan and carry out attacks on their own,
without direct ties to specific organizations.
This type of threat is particularly difficult to identify in advance.
Organizations need to develop scenario-based response frameworks
and strengthen employee training and systems
for recognizing early warning signs and unusual behavior.
05. Threat expansion via social media and AI
With the rapid development of generative AI,
false and manipulated information is spreading faster and more widely.
We are seeing a growing number of cases
of reputation attacks, exposure of personal information,
and online harassment targeting specific companies or individuals.
There is also a higher risk that publicly available information
will be misused to exploit sensitive personal data.
In response, companies need to strengthen their frameworks
for managing online information exposure and corporate reputation.
Connected threats and the evolution of security strategy
Today’s security threats do not exist in isolation.
They are interconnected and act in combination.
In this environment, it is increasingly important
to use data-driven insights and professional analysis
to understand and anticipate threats in advance.
Conclusion
The security environment in 2026 is expected to become
even more complex and difficult to predict.
However, these changes also present an opportunity
to develop more structured and mature security strategies.
As organizations work to understand and prepare for future risks,
a connected, holistic perspective on security
will become a key guiding principle.
