The Risk Landscape Has Changed

Collaboration Platforms Are Critical Digital Infrastructure

Messaging platforms are no longer just everyday productivity tools. They contain executive discussions, incident response coordination, operational strategy, and sensitive or even classified data.

At the same time, the risk landscape is shifting:

Geopolitical tensions are redefining digital sovereignty requirements

 
 European leaders and cloud customers are increasingly questioning their reliance on U.S. cloud infrastructure, with European banks shifting workloads to EU-based cloud providers amid concerns over U.S. data access laws such as the Cloud Act.

Supply chain attacks have compromised collaboration emvironments 

 
Token theft and identity risks have impacted Microsoft Teams, while breaches in Slack have resulted in major data exposure, including the leak of 1TB of Disney’s data.

 Compliance standards are tightening across Europe, raising security expectations  

 

Regulations such as  NIS2  and  DORA are elevating requirements for encryption, operational resilience, and risk management, with significant penalties for non-compliance. 
 

 

When digital collaboration becomes mission-critical infrastructure, security cannot rely on assumed trust. Security must be architectural, not optional. 

Modern Collaboration, Outdated Security

Why MS Teams and Slack Fall Short

Traditional collaboration tools weren’t built for sensitive, regulated communication.

When privacy, compliance, and control matter, their architecture creates exposure.

Slack Wasn’t Built for Confidential Collaboration

Slack is designed for openness and integrations rather than privacy-first security. Messages are not end-to-end encrypted by default, administrators can access content, and third-party apps expand the attack surface. 

MS Teams - Security by Policy, Not by Design

Teams provides extensive admin controls but does not enable end-to-end encryption by default, and its reliance on big-tech infrastructure introduces potential sovereignty risks. 

For organizations that require true confidentiality, that compromise becomes a risk.

When Confidentiality and Architecture Matter

Why Security-First Organizations Choose Wire
