Google’s open-source HEIR lets AI work with data it can’t see

Google open-sourced HEIR, a compiler toolchain that converts pre-trained AI models to operate on homomorphically encrypted data without exposing it.

Google's HEIR (Homomorphic Encryption Intermediate Representation) is an open-source compiler toolchain and development platform for fully homomorphic encryption, announced in 2023 and now supporting four peer-reviewed publications. It compiles Python programs handling sensitive data into implementations that process encrypted inputs, supporting multiple FHE schemes, libraries, front-end languages, and hardware accelerators such as GPUs, TPUs, FPGAs, and custom ASICs. Demonstrated applications include private recommendations, credit card fraud detection, network intrusion detection, and hotword recognition.

Mars Security brings threat intelligence to detection in real time

Mars Security launched Real-Time Intel-Based Detection, converting advisories from CISA and Mandiant into backtested MITRE ATT&CK-mapped detection rules for CrowdStrike, Wiz, and Splunk.

Mars Security announced a capability that automatically turns newly published threat intelligence from sources like CISA, Mandiant, Unit 42, and Microsoft into MITRE ATT&CK-mapped detection rules. Each rule is written in the native query language of the customer's telemetry (CrowdStrike Falcon, Wiz, Splunk, firewalls, identity providers, AWS, Snowflake, Databricks) and backtested against 30 days of the customer's data before deployment, with indicator scoring to drop noisy or stale indicators. The platform also maps existing detection coverage, flags gaps such as AWS CloudTrail tampering and pass-the-hash movement, and delivers some recommendations as open pull requests for detection-as-code workflows.

Mars Security Launches Real-Time Intel-to-Detection Engine That Turns Live Threat Intelligence Into Backtested Detections in Minutes

Mars Security launched Real-Time Intel-Based Detection, converting advisories into MITRE ATT&CK-mapped, backtested detection rules for CrowdStrike, Wiz, and Splunk within minutes.

The capability turns newly published threat intelligence from CISA, Mandiant, Unit 42, and Microsoft Threat Intelligence into validated detection rules within minutes, each backtested against 30 days of the customer's own telemetry before deployment. Rules are written in native query languages across CrowdStrike Falcon, Wiz, Splunk, firewalls, Linux Sysmon, identity providers, AWS telemetry, and data lakes such as Snowflake and Databricks, with no data ingestion or stack changes. The feature is available at no additional cost to existing customers and on AWS Marketplace. Mars also flags detection coverage gaps and extends monitoring to credentials leaked by AI coding agents.

Product showcase: GitGuardian Honeytoken catches credential theft as it happens

GitGuardian now deploys honeytoken decoy AWS credentials across developer fleets via MDM, generating high-fidelity alerts when infostealers test stolen credentials.

GitGuardian extended its honeytoken platform so decoy AWS credentials can deploy fleet-wide to developer laptops through existing MDM tooling, with deleted decoys automatically replaced at the next sync. When a harvester tests a decoy, the platform logs the API call in the controlling AWS account and raises an incident naming the source machine and file, routed via email, Slack, Teams, ServiceNow, or webhooks. The capability responds to infostealers such as Shai-Hulud that scan entire filesystems and validate stolen credentials within seconds. GitGuardian is building decoys for Kubernetes and package registry credentials using random, structure-free identifiers that resist detection.

Attack Chains, Not Just Attack Surfaces: Why Testing Individual Techniques Misses the Point

Filigran introduces Attack Chaining in OpenAEV to continuously simulate multi-stage attack paths, exposing gaps that isolated MITRE ATT&CK technique testing misses.

Filigran announced Attack Chaining, a new scenario type in its OpenAEV platform that links individual techniques into automated, continuously-run multi-stage attack paths, using each step's real output (credentials, tokens, open ports) to branch dynamically toward a final objective. The article cites Filigran's State of Threat Management report, in which 93% of security leaders reported a business-impacting cyberattack in the past 12 months, 88% said AI accelerates attackers, and 84% blamed siloed tools and disconnected testing. The 2025 DGFiP breach is cited as an example where individually survivable weaknesses chained into a major intrusion. The feature includes conditional chaining logic, live attack path mapping, structured findings for identifying chokepoints, and predefined scope and safety guardrails.

Bitsight connects threat intelligence and exposure monitoring across the supply chain

Bitsight made Beacon generally available, combining supply-chain exposure monitoring with MCP support to feed threat intelligence into AI workflows.

Bitsight announced general availability of Beacon, which continuously monitors critical vendors for exposure, vulnerabilities, malicious activity, intrusion, stolen credentials and compromise. New Model Context Protocol (MCP) and agentic capabilities push Bitsight intelligence into AI-enabled workflows, with over 400 customers signing up for early access in one month. The company cites data that third parties now account for almost half of enterprise breaches, up over 60% year over year.

AWS makes it easier to spot firewall rules that have gone quiet

AWS Network Firewall added rule hit counts for stateful rules, letting teams identify unused rules and validate control effectiveness at no added cost.

AWS Network Firewall's rule hit count capability gives security teams visibility into which stateful firewall rules are matching traffic, helping identify unused or redundant rules and validate controls for compliance frameworks like PCI DSS 4.0 and DORA. The feature covers stateful rules in custom and managed rule groups, is enabled by default at no additional Network Firewall cost, and is available in all supported Regions except UAE and Bahrain. Data is surfaced in the Network Firewall dashboard's Top Rule Hits view and can be queried via CloudWatch Logs Insights or Amazon Athena.

Proactive cyber defense for governments and enterprises

Google launches the Fairwind Program giving governments and enterprises access to Gemini 3.8 Flash Cyber and CodeMender for autonomous vulnerability discovery and patching.

Google announced the Fairwind Program, a limited-access offering bringing its cyber defense capabilities to government agencies, critical infrastructure operators, and trusted partners, with more than 650 participating organizations. It combines the Gemini 3.8 Flash Cyber model with the CodeMender harness to autonomously find, verify, and fix vulnerabilities, generating deployment-ready patches in minutes inside customers' cloud environments. Google also raised its total cybersecurity funding commitment above $100 million, including $36 million granted to 35 US cyber clinics supporting hospitals, school districts, and municipal utilities.
