- AI security ARR from Prompt Security and Purple AI tripled year over year.
What critics are saying
- May 2026 restructuring cut 8% of staff, signaling persistent cost pressure.
- The Johansson securities appeal remains pending after October 2025 dismissal.
- CrowdStrike and Microsoft bundle broader platforms; SentinelOne risks endpoint commoditization by 2027.

↓ -8%OpenAI launched Daybreak for Frontline Defenders on 3 September, committing $1 billion in subsidized access, training, and partnerships. The Daybreak Defense Network now includes over 35 enterprise products and services. Cloudflare is offering invitation-only access to an AI vulnerability-discovery and remediation service built with GPT-5.6 Cyber. SentinelOne is adding Daybreak models to its Wayfinder services. Both companies take different approaches to the same programme. Cloudflare's model starts at the network and developer edge, combining source-code analysis with traffic and security context. SentinelOne approaches from endpoint and security operations, placing AI inside workflows for security teams. Eighty-seven hedge funds held Cloudflare at 30 June, versus 84 at 31 March. Forty-one held SentinelOne in Q2, up from 37 in Q1.
SentinelOne has expanded its Wayfinder Frontier AI Services to run on OpenAI Daybreak models, starting with GPT-5.6-Cyber. The endpoint and cloud security vendor introduced two new capabilities: one scans customer code repositories for OWASP-class flaws, implants, exposed secrets and supply-chain risks, with findings mapped to MITRE ATT&CK; the other evaluates telemetry against detection rules to identify posture gaps, including risky use of VPNs, proxies and remote-management tools. SentinelLABS benchmarking found GPT-5.6-Cyber performed best in class on reverse engineering and analysis of military-grade malware. The company's offensive-security analysts validate every verdict before delivery to customers. "Attackers are increasingly using AI to find and exploit weaknesses," said Chief Customer Officer Steve Stone.
SentinelOne has emerged as a stock to watch among Wall Street's favourites, according to StockStory's latest analysis. The AI-powered cybersecurity company, which provides autonomous threat detection across endpoints and cloud systems, carries a consensus price target implying 20.6% upside. However, the analysis warns investors to be cautious about two stocks despite bullish Wall Street targets. MGP Ingredients faces declining fundamentals, with revenue down 14.6% annually over three years and earnings per share dropping 22% annually. Its free cash flow margin fell 9.5 percentage points last year. American Outdoor Brands has seen annual revenue decline 7.1% over five years. The outdoor products company operates with a low 5% free cash flow margin. StockStory emphasises the importance of independent analysis, noting that institutional pressures can lead analysts to overly optimistic forecasts.
SentinelOne reported strong second-quarter results on 27 August, with revenue growing 21% to $292 million and annualised recurring revenue (ARR) increasing 22% to $1.22 billion. Non-GAAP earnings per share doubled to $0.08. Despite the positive performance, shares fell in extended trading as investors focused on trimmed profit guidance and high restructuring costs. However, Scotiabank analyst Patrick Colville raised the firm's price target to $26 from $23.50, maintaining an Outperform rating. The key signal, according to Scotiabank, was management's revised guidance for fiscal 2027 ARR growth to mid-single digits from low-single digits. Net new ARR came in at $56 million, up 4% year-over-year. Not all analysts share this optimism. DA Davidson called underlying trends "lacklustre" and anticipates further deceleration ahead.
SentinelOne, a cybersecurity company leveraging AI for automated enterprise protection, has seen its stock rise 47% this year while trading under $25 per share. The company reported $1.2 billion in annual recurring revenue for its fiscal Q2 2027, up 22% year-over-year, with AI-related revenue nearly tripling. SentinelOne's Singularity platform protects endpoints, cloud networks, and AI applications. Its AI security tools include Prompt Security, which guards against prompt injection attacks, and Purple AI, an autonomous threat response assistant. The company reduced its GAAP net loss by 39% to $169.5 million in the first half of fiscal 2027. Excluding non-cash expenses, it posted a profit of $40.7 million. SentinelOne's stock trades at a price-to-sales ratio of 6.6, significantly below competitors CrowdStrike (41.6) and Palo Alto Networks (25.6).
