AI security firm, depthfirst, announces $40 million Series A

$40M for "AI-native platform to fight threats" is consultant-speak for "we hired an ML team." That's not a business model, it's a headcount bet.

AI security's the right problem — threat detection, anomaly patterns. But the real test is: do their detections beat traditional SIEM plus human analysts? That takes 18 months to prove.

$40M Series A suggests either late-stage valuation spike or investor FOMO. Either way, demand proof before trusting the bet.
