The problem
Signature-based scanning misses malware it hasn't seen before by definition — a file with no known signature passes a static scan even if it behaves maliciously the moment it runs.
Attackers know this, and modify existing payloads slightly specifically to avoid matching a known signature, without changing what the file actually does once it executes.
Scanning after a file has already reached a device is too late to prevent the first execution; the verdict needs to exist before delivery, not after.
How MaskFlare Sandbox works
Sandbox executes unknown files in an isolated cloud environment and inspects their actual runtime behavior, holding delivery until the verdict is in.
Benefits
Catches what signatures miss
Behavioral analysis flags malicious action even from a file with no known signature.
Delivery held until verdict
Files aren't released to the endpoint until detonation completes, not scanned after the fact.
No production system at risk
Detonation happens in a disposable, isolated environment, never on infrastructure that matters.
Resistant to signature evasion
Behavior-based verdicts aren't defeated by minor modifications designed to dodge a known signature.
Capabilities
Isolated detonation environment
Unknown files execute in a disposable cloud environment, fully isolated from production systems.
Behavioral analysis
Runtime behavior, more than a static signature, determines the verdict.
Multi-stage payload detection
Observes behavior through multiple execution stages, catching payloads that only reveal malicious behavior after an initial delay.
Verdict-gated delivery
Files are held until detonation completes; nothing reaches a device before a verdict exists.

Frequently asked questions
What is a cloud sandbox?
A cloud sandbox is an isolated environment where an unknown file is executed and observed, so what it actually does at runtime — beyond any static signature — determines whether it's safe to deliver.
How long does detonation take?
Most files receive a verdict quickly enough that delivery isn't noticeably delayed; more evasive samples may take longer to fully observe.
Can malware detect that it's running in a sandbox and behave differently?
Some malware attempts exactly this. Detonation environments are designed to resist common sandbox-evasion techniques, though this is an ongoing arms race rather than a solved problem.
Does Sandbox replace antivirus on the endpoint?
No — it complements endpoint protection by catching unknown threats before delivery, rather than relying solely on detection after a file has already arrived.
What types of files does Sandbox inspect?
Common categories include documents, archives, and executables — anything that could carry a payload and isn't already known-safe.
