Insight Partners begins alerting victims after January hack revealed deep data exposure
As the New York investment giant notifies affected individuals, questions linger about cybersecurity vulnerabilities across private equity — and what it means when the investors get hacked.
Insight Partners, the multi-billion-dollar venture capital firm known for backing Israeli tech juggernauts like monday.com, Armis, and Wiz, is still reeling from a cyberattack it disclosed in January. Nearly four months later, the firm has begun notifying individuals whose data may have been exposed—but much about the breach remains murky, including its full scope, the number of affected parties, and what concrete measures are being taken in its aftermath.
In a brief online update published this week, Insight said it would begin notifying affected individuals on a “rolling basis” and that the compromised data may include fund information, internal banking and tax records, and personal data tied to employees, limited partners, and portfolio companies. The firm emphasized that the review is ongoing and has brought in third-party experts, including a forensic and eDiscovery team, to aid in the investigation.
Yet the long silence—and the fact that affected parties are only now being formally notified—has raised concerns in some corners of the industry, particularly given the nature of the data at stake.
The January breach, which Insight attributed to a “sophisticated social engineering attack,” is notable not just for its timing—coming days after the firm announced a $12.5 billion fundraise—but for its target. Insight has invested in more than 100 Israeli startups, many of them in sensitive cybersecurity domains. A successful intrusion into Insight’s internal systems risks exposing strategic roadmaps, investor details, and possibly even proprietary technologies from some of the world’s most security-conscious companies.
As of the last update, Insight said there was “no evidence” the threat actor remained in its systems after January 16, and no operational disruption has been reported. Still, the incident underscores the uncomfortable reality that even firms embedded in the cybersecurity ecosystem are vulnerable.

Insight was quick to alert its investors and portfolio companies via private channels in January, but its public response has been far more reserved. The firm waited weeks before confirming the breach publicly and has offered only high-level details since. The firm’s latest update, though more substantive, reiterates that formal notifications are only just beginning—months after the attack occurred.
