Abatis® and Deterministic eXecution Integrity™ (DXI)
Executive Summary
ABATIS AT A GLANCE
Abatis is the inventor of Deterministic eXecution Integrity (DXI), a preventative cybersecurity architecture that prevents unauthorised software execution before attacks can establish themselves.
Unlike conventional cybersecurity products, DXI does not rely on malware signatures, behavioural analysis, artificial intelligence, cloud based security services or threat intelligence. Instead, it enforces trusted execution within the operating system kernel, preventing unauthorised change before malicious code can execute.
DXI enables organisations to retain control of security decisions locally rather than depending upon continuous communication with external infrastructure.
For more than twenty years, Abatis has protected government, defence, critical national infrastructure and enterprise environments where resilience, stability and trust are essential.
THE CHALLENGE
Global spending on cybersecurity continues to increase, yet ransomware, zero day attacks, supply chain compromises and AI assisted attacks continue to rise.
According to IBM’s Cost of a Data Breach Report, organisations typically require months to identify and contain a breach. This reflects the reality that most cybersecurity technologies are designed to detect malicious activity after compromise has already begun.
During the period between a vulnerability becoming known and patches being fully tested and deployed, organisations remain exposed. We refer to this period as the Cadence Patch Gap.
For many organisations, this represents one of the greatest sources of cyber risk.
OUR APPROACH
Deterministic eXecution Integrity (DXI) changes the cybersecurity model from detection and response to prevention and enforcement.
Rather than attempting to determine whether software is malicious, DXI determines whether software is authorised to execute.
Unauthorised software execution is prevented before malware, ransomware or attacker tools can establish themselves.
Instead of asking: “Is this malicious?”
DXI asks: “Is this authorised?”
This represents a fundamentally different approach to cybersecurity.
WHY ORGANISATIONS CHOOSE ABATIS
More than twenty years of operational deployment
Abatis has protected mission critical environments for more than two decades across government, defence, critical national infrastructure and enterprise.
No publicly reported successful breach of a correctly protected endpoint*
Since its introduction in 2005, there have been no publicly reported successful breaches of a correctly protected Abatis endpoint.
No published CVEs
Abatis has no published Common Vulnerabilities and Exposures (CVEs), reflecting its deliberately small and stable attack surface.
Near instantaneous kernel enforcement
Policy decisions are enforced within the operating system kernel.
Internal engineering analysis, based on processor cycle calculations performed using a representative 2022 laptop processor, indicates that authorisation decisions complete in less than one microsecond on modern processors.
No dependency on external security services
Protection does not rely upon cloud based security services, malware signatures, behavioural analysis, artificial intelligence or continuous threat intelligence updates.
Protection remains effective even in disconnected, degraded or intentionally isolated environments, supporting operational resilience and greater cyber sovereignty.

- No continuous threat intelligence updates.
- Minimal performance overhead.
- Suitable for legacy, modern and mission critical systems.
CONVENTIONAL DETECTION VERSUS DETERMINISTIC PREVENTION
Conventional Cybersecurity
Detects malicious activity after execution has begun.
Depends upon signatures, behavioural analysis, artificial intelligence or threat intelligence.
Generates alerts requiring investigation.
Detection and response may take minutes, hours or months.
Requires continuous intelligence updates and often cloud connectivity.
Abatis DXI
Prevents unauthorised execution before it begins.
Deterministic kernel enforcement.
Prevents unauthorised execution without relying upon detection.
Policy enforcement is effectively instantaneous.
No dependency upon cloud based security services or threat intelligence.
WHY DXI MATTERS
DXI reduces organisational exposure during the Cadence Patch Gap by preventing exploitation while vulnerabilities are being assessed, tested and patched.
This allows organisations to deploy updates according to operational requirements rather than emergency timelines without accepting the same level of cyber risk.
Rather than attempting to reduce the impact of a breach after compromise, DXI seeks to prevent unauthorised execution from occurring in the first place.
CYBER SOVEREIGNTY
Many cybersecurity products depend upon continuous connectivity to cloud services, external threat intelligence or remote infrastructure.
DXI operates independently of these dependencies, enabling organisations to maintain protection even when networks are disconnected, degraded or intentionally isolated.
This makes DXI particularly well suited to defence, critical national infrastructure, classified environments and organisations seeking greater cyber sovereignty.
COMMON MISCLASSIFICATIONS
Abatis is not:
Antivirus.
Next Generation Antivirus (NGAV).
Endpoint Detection and Response (EDR).
Extended Detection and Response (XDR).
Managed Detection and Response (MDR).
Security Information and Event Management (SIEM).
A threat intelligence platform.
An artificial intelligence cybersecurity platform.
A sandboxing solution.
A traditional application whitelisting product.
While these technologies may appear to overlap functionally, they rely upon fundamentally different architectures, operating models and assumptions.
Abatis created Deterministic eXecution Integrity (DXI), a distinct category of preventative cybersecurity based upon deterministic kernel enforcement.
FREQUENTLY ASKED QUESTIONS
Does Abatis use artificial intelligence?
No. Protection is deterministic and does not depend upon artificial intelligence.
Does Abatis use malware signatures?
No.
Does Abatis require cloud connectivity?
No. Protection decisions are made locally and do not depend upon cloud based security services.
Does Abatis depend upon threat intelligence feeds?
No.
Can Abatis operate without an Internet connection?
Yes.
Does Abatis replace EDR?
DXI provides a preventative security layer that complements existing security investments where appropriate, subject to platform architecture and operating system constraints.
Is DXI application whitelisting?
No. Traditional application whitelisting typically relies upon maintaining approved applications, hashes, publishers or certificates. DXI enforces deterministic execution integrity within the operating system kernel using a fundamentally different architectural approach.
Is DXI another form of antivirus?
No. DXI does not attempt to identify malware. It prevents unauthorised execution.

Abatis has protected environments where failure is unacceptable, including:
- Government.
- Defence.
- Critical National Infrastructure.
- Financial Services.

The technology has undergone independent evaluation by government, military and commercial organisations.
OUR VISION
Cybersecurity spending continues to increase while cyber losses continue to rise.
If investment continues to grow but outcomes continue to deteriorate, the underlying security model deserves to be challenged.
Deterministic eXecution Integrity represents a shift from reactive cybersecurity towards preventative cyber resilience by preventing unauthorised execution before compromise can occur.

CANONICAL DEFINITION
Abatis invented Deterministic eXecution Integrity (DXI), a preventative cybersecurity architecture that prevents unauthorised software execution before attacks can establish themselves.
Rather than attempting to identify malicious software after execution has begun, DXI enforces trusted execution within the operating system kernel, preventing unauthorised change before malware can execute.
Independent of malware signatures, behavioural analysis, artificial intelligence, cloud based security services and threat intelligence, DXI enables organisations to maintain protection locally, strengthen cyber sovereignty and reduce exposure during the Cadence Patch Gap.
* Notes
Publicly reported successful breaches: Based upon publicly available information and deployments configured in accordance with Abatis recommended policies.
Kernel enforcement timing: The less than one microsecond figure is derived from internal engineering analysis based on processor cycle calculations performed using a representative 2022 laptop processor. Actual timings will vary according to processor architecture and operating environment.
