Short answer: in 2027, secure file sharing shifts from implementing to proving. It is the first full year under NIS2 in the Netherlands, the AI Act’s high-risk rules and the Cyber Resilience Act’s main obligations follow in December, and supply chain partners and shadow AI become the biggest leaks. The seven trends in this article show what IT and compliance decision-makers should steer on in 2027: evidence per transfer, control over the supply chain, a clear route for AI, strong recipient verification and a shorter lifespan for sensitive files.
Published on 11 November 2026
Which secure file sharing trends will shape 2027? Most of the rules are in place. The question now is whether organisations can show that they work, exactly at the moment sensitive files leave the organisation. In this article we list seven trends, with the facts and deadlines that matter and a decision question for your own organisation per trend.
Curious how 2026 went? Then first read our review of the secure file sharing trends of 2026.
2027 at a glance
| When | What happens | What it means for file sharing |
|---|---|---|
| All of 2027 | First full year under the Dutch Cybersecurity Act (NIS2) and the Critical Entities Resilience Act | Supervisors ask for evidence that measures work |
| Mid-2027 | Banks and public services must accept the European Digital Identity Wallet for strong authentication | New ways to verify recipients |
| 2027 | Negotiations on the Digital Omnibus: one reporting point for incidents and new rules for breach notification | Incident files must be fast and complete |
| 2 December 2027 | AI Act: obligations for stand-alone high-risk AI systems | Control over which data goes into AI applications |
| 11 December 2027 | Cyber Resilience Act: most obligations apply | Stricter requirements when buying software |
Trend 1: from implementing to proving
The Dutch Cybersecurity Act and the Critical Entities Resilience Act have applied since 15 August 2026 to over 8,000 organisations in 18 sectors (Dutch government, Dutch source). 2027 is the first full year in which they apply. The board is ultimately responsible and must approve the measures. That makes the question concrete: can you show for every external transfer who had access, under which conditions and for how long?
Decision question: how quickly can you show a complete audit trail for any file that left the organisation last month?

Trend 2: the supply chain becomes the biggest leak
According to the Verizon Data Breach Investigations Report 2026, third parties were involved in 48% of breaches, an increase of 60% compared with a year earlier. Suppliers, advisers, accountants and supply chain partners receive more and more sensitive information. Under NIS2 and DORA, control over that supply chain is part of the duty of care.
For secure file sharing this means: share only what each party needs, with named recipients and an expiry date, and record per transfer who received what. How secure sharing with supply chain partners also drives growth is explained in secure data sharing: 5 applications for growth.
Decision question: which three supply chain partners receive your most sensitive information, and through which channel?
Trend 3: shadow AI becomes a data problem
AI has quickly become an everyday tool. According to the DBIR 2026, 45% of employees are regular AI users on a corporate device, up from 15% a year earlier, and 67% use a non-corporate account to do so. That makes shadow AI the third most common non-malicious insider action in DLP data. Sensitive files end up outside the organisation’s view.
On 2 December 2027, the AI Act rules for stand-alone high-risk AI also take effect, after being postponed by the Digital Omnibus. Organisations using AI need to know which data goes into it.
Decision question: which documents must never go into an external AI tool, and do employees have an equally easy alternative?
Trend 4: one reporting point, less time searching
In its Digital Omnibus of November 2025, the European Commission proposed one reporting point for incidents under the GDPR, NIS2 and DORA among others, and to report personal data breaches only when the risk is high, within 96 hours instead of 72 (Jones Day). The Council agreed its position on 21 October 2026. In 2027, the Council and the European Parliament will negotiate the final text. Until then, the current deadlines apply.
Whatever the outcome: one report for several supervisors requires an incident file that is complete quickly. If you can see immediately who downloaded a misdirected file, you report on facts instead of assumptions.
Decision question: how many hours does it currently take to establish which files were shared with whom during an incident?
Trend 5: the recipient must prove who they are
The DBIR 2026 shows attackers shifting: credential abuse was the first step in 13% of breaches, exploiting vulnerabilities in 31%. At the same time, AI makes phishing emails more convincing. An email address alone is therefore no proof of identity.
New tools are coming. Member states must offer a European Digital Identity Wallet by the end of 2026, and banks and public services must accept it for strong authentication by mid-2027 (Biometric Update). The Netherlands may be behind schedule. For now, verifying external recipients with a one-time code, an authenticator or a PIN remains the practical standard.
Decision question: how do you verify an external recipient today whom you have never spoken to?
Trend 6: files with an expiry date
Under the EU roadmap for post-quantum cryptography, member states should start the transition by the end of 2026, and critical infrastructure should complete it by the end of 2030 at the latest. The reason is the risk of “harvest now, decrypt later”: encrypted data intercepted today may become readable in a few years.
For secure file sharing this mainly means: the shorter a sensitive file exists, the smaller the risk. Temporary access, automatic deletion and short retention periods therefore also become a long-term measure. Also ask suppliers about their plans for post-quantum cryptography.
Decision question: which shared files must still be confidential in ten years, and how long are they online now?
Trend 7: sovereignty and the software supply chain in procurement
On 11 December 2027, most obligations of the Cyber Resilience Act take effect. Manufacturers must then show that their software is designed and maintained securely. At the same time, organisations increasingly ask where data is stored and who has administrative access. Both questions come together in procurement: who supplies the software, where does it run and how is it updated?
Decision question: are requirements for data location, security updates and incident reporting already in your 2027 procurement terms?
What you can do in 2027: five steps
- Map your external document flows. Which information goes to which parties, and through which channel?
- Choose one approved route for sensitive exchange, with verification, an expiry date and an audit trail.
- Agree on AI. Record which information must never go into external AI tools and offer a secure alternative.
- Practise an incident. Reconstruct a fictitious misdirected transfer and measure how long it takes.
- Assess your suppliers on data location, updates and their plans for post-quantum cryptography.

How Msafe helps with the trends of 2027
Each of the secure file sharing trends for 2027 requires control at the moment a file leaves the organisation. Msafe Secure File Transfer is built for sharing sensitive files with external parties, without employees having to change the way they work:
- Evidence per transfer: an exportable audit trail of uploads, downloads and shares.
- Control over the supply chain: named recipients, an expiry date per share and access you can revoke as long as the file has not been downloaded.
- Recipient verification: for example with a one-time code via phone, an authenticator or a PIN, or without an account via Easy Download.
- Easy for employees: sharing from Outlook with the Msafe Connector, Single Sign-On via Microsoft Entra ID and files up to 1 TB as standard.
- Central rules: retention periods and excluded file types set centrally, users assigned automatically via SCIM.
Msafe is a Dutch company, hosts in the Netherlands and is certified to ISO/IEC 27001:2022. A tool never makes an organisation compliant automatically, but it does make file sharing demonstrably controlled.
Frequently asked questions about secure file sharing trends 2027
Secure file sharing trends 2027: legislation and deadlines
The shift from implementing to proving under NIS2, supply chain partners as the biggest risk, shadow AI, one reporting point for incidents, stronger recipient verification, a shorter lifespan for sensitive files and stricter supplier requirements under the Cyber Resilience Act.
On 2 December 2027 the AI Act rules for stand-alone high-risk AI take effect, and on 11 December 2027 most obligations of the Cyber Resilience Act. By mid-2027, banks and public services must accept the European Digital Identity Wallet.
That is not yet certain. The European Commission proposed 96 hours for high-risk personal data breaches and one reporting point for several laws. The Council agreed its position in October 2026, but the Council and Parliament still need to reach agreement. Until then, the current 72-hour deadline applies.
Secure file sharing trends 2027: risks and measures
Shadow AI is the use of AI tools outside the organisation’s view, for example with a personal account. According to the Verizon DBIR 2026, 67% of AI users do so with a non-corporate account. Sensitive documents can leave the organisation without anyone noticing.
Start with insight: which shared files must remain confidential for a long time? Limit how long they are available and ask suppliers about their plans for post-quantum cryptography. The EU roadmap asks member states to start the transition by the end of 2026.
No. Secure file sharing supports measures such as verification, temporary access, logging and retention periods. Compliance also depends on policy, risk analysis and processes.
