SaaS & Technology
Executive impersonation, hijacked vendor threads and cloud credential phishing, with organisation-specific detection built and tuned in-house.
The challenge
SaaS and technology companies run on cloud identity: a single harvested SSO or workspace credential can reach source code, customer data and production systems. Attackers targeting these organisations increasingly write mail well enough to pass a reader's own judgement, hijacking real vendor threads or impersonating executives rather than relying on obviously malicious content. Centralised detection models that are retrained on a fixed cycle leave a gap between when a new tactic appears and when coverage catches up — a gap that moves faster than most vendor release schedules.
The same generalisation works against day-to-day operations: when a legitimate vendor or customer email is wrongly flagged, the only route to a fix is a support ticket, while sales cycles, invoicing and customer communications wait on the outcome. Meanwhile, security teams absorb a steady stream of user-reported email that has to be triaged by hand, work that scales with headcount rather than with risk.
Key use cases
Executive impersonation detection
Detections are tailored to the organisation's own executives, communication style and reporting lines using natural language understanding, so a convincing but fraudulent message from a senior leader's account is judged against how that person and their team actually communicate, not a generic impersonation pattern.
Hijacked vendor thread detection
Because coverage is built around an organisation's actual vendor relationships and communication history, a thread hijacked mid-conversation — where the content and tone otherwise look legitimate — can still be assessed against what normal correspondence with that vendor looks like.
SSO and cloud credential phishing detection
Sign-in lures that copy an organisation's own SSO branding and login flows are analysed through content and live link navigation, addressing the credential-harvesting pages that pose the most direct risk to cloud-hosted code, data and infrastructure.
Organisation-specific coverage
ADÉ (Autonomous Detection Engineer) builds and deploys detections tuned to the company's own environment rather than a single model shared across every customer, so targeted, context-rich attacks that generic tools miss are more likely to be caught.
Autonomous abuse-mailbox triage
ASA (Autonomous Security Analyst) investigates and resolves user-reported email in around a minute, removing hours of daily manual sorting so the security team focuses on genuine threats rather than working through a queue.
Transparent detection and tuning
Every decision traces to a specific signal and message, so when a legitimate vendor or customer email is affected, the team can see why and adjust the exception themselves rather than waiting on a vendor response.
Core capabilities
Distributed Detection Model
Builds coverage tailored to each organisation's vendors and communication patterns instead of one shared model.
Autonomous Detection Engineer (ADÉ)
Generates and deploys new, organisation-specific detections in hours as attackers iterate.
Autonomous Security Analyst (ASA)
Clears the abuse mailbox by triaging and resolving user-reported messages without manual review.
Explainable decisions
Shows the exact signal and content behind every verdict, enabling fast, self-service resolution.
API-based deployment
Connects to Microsoft 365 and Google Workspace without MX record or SPF/DMARC changes.
A hijacked vendor thread requesting payment details
An existing SaaS vendor's mailbox is compromised elsewhere, and attackers reply into a genuine, ongoing thread with the finance team, asking for an invoice to be redirected to a new account. The content reads naturally because it is grafted onto a real conversation. Coverage built around the vendor's usual communication pattern flags the mismatch between the request and how that vendor's billing correspondence normally looks, and the message is surfaced for review rather than actioned automatically. The finance team can see the specific signals — the payment-redirect language against the vendor's history — and confirms the block, avoiding a fraudulent payment without disrupting the rest of the relationship.

- 2A mismatch in payment-related content triggers a review hold
- 3Finance confirms the block using the explained reasoning, no ticket required
Expected outcomes
- Reduced exposure to executive impersonation and hijacked vendor threads
- Faster deployment of coverage for new, organisation-specific attack patterns
- Less analyst time spent triaging user-reported email manually
- Self-service resolution of false positives affecting genuine vendor or customer mail
- Detection tuned to the company's actual workflows rather than a one-size-fits-all model
How CyberLane helps
CyberLane helps SaaS and technology organisations work out which of their own workflows — vendor billing threads, executive communications, SSO branding — are worth encoding as custom detections, and how Sublime should sit alongside existing identity and SOC tooling. We support the business case, plan a proof of concept against real inbound and reported traffic, and provide implementation oversight, while leaving product configuration and deployment work to Sublime or a qualified implementation partner.
- Assessment of executive-impersonation and vendor-thread exposure specific to the business
- Business case and proof-of-concept plan aligned to engineering and finance workflows
- Guidance on integration with existing SOC and identity tooling
- Implementation oversight coordinated with Sublime or a qualified partner
CyberLane is independent and works on the decision rather than the deployment. Product-specific delivery is coordinated with the vendor or a qualified implementation partner.
