Company profile
researched Aug 2026DUPLICATE ENTRY NOTE: This database row (profile_id 10089868, name 'Awake Security', domain awakesecurity.com) is a DUPLICATE of a company already fully researched and ingested under profile_id 10020186 earlier in this project. That earlier row originated from a garbled/corrupted source database entry that listed the name as 'Untangle' with website 'arista.com' -- an internally inconsistent combination, since the real firewall company Untangle (untangle.com, founder Dirk Morris, investors Rustic Canyon Partners/CMEA Capital, no confirmed Greylock relationship) is a distinct entity from Awake Security. After investigation, that earlier row was resolved to represent Awake Security, the genuine Greylock-backed NDR company that was separately and confirmably acquired by Arista Networks in 2020 (the 'arista.com' field was coincidentally correct for the true underlying company, even though the 'Untangle' name was not). This new row, 10089868, is a second, direct, non-garbled database entry for the same real-world company (name 'Awake Security', domain 'awakesecurity.com' given cleanly in the source data), meaning the same company now exists twice in this database under two different profile_ids: 10020186 (originally mislabeled 'Untangle'/arista.com, since resolved) and 10089868 (this row). All facts below are independently re-verified and are consistent with, not contradictory to, the data recorded under 10020186.
Awake Security was founded in September 2014 (initially based in Mountain View, later headquartered in Santa Clara, California) by Debabrata Dash, Gary Golomb, Keith Amidon, and Michael Callahan (who served as Co-founder & CEO in the company's early years). The company built an AI- and machine-learning-driven network detection and response (NDR) platform centered on a proprietary 'Security Knowledge Graph' data model, which modeled network entities (devices, users, applications) rather than relying purely on IP-address-based analysis, enabling security teams to detect insider threats, corporate espionage, lateral movement, and data exfiltration with full forensic context across on-premises, IoT, and cloud network traffic. Crunchbase describes the platform as 'a network traffic analysis platform that combines artificial intelligence with human expertise to hunt for both insider and external attacker behaviors, while providing full forensics across traditional, IoT and cloud networks for autonomous triage and response.'
Greylock Partners invested in Awake Security's roughly $30M+ growth round announced July 17, 2017, alongside Bain Capital Ventures; Greylock partner Asheem Chandna and Bain Capital Ventures' Enrique Salem both joined Awake's board as part of that round (per FinSMEs' contemporaneous funding announcement, which explicitly names both Greylock Partners and Asheem Chandna). Greylock continued as an investor through Awake's $36 million Series C round, announced April 15, 2020, which was led by Evolution Equity Partners (whose partner Karthik Subramanian joined the board) with participation from Energize Ventures, Liberty Global Ventures, and existing investors Bain Capital Ventures and Greylock Partners. This was independently re-confirmed via a direct fetch of the FinSMEs Series C article, which lists the same investor set, board members (Asheem Chandna, Enrique Salem, Kevin Mandia, plus new addition Karthik Subramanian), and CEO Rahul Kashyap. By the time of the Series C, cumulative funding was reported as 'nearly $80 million,' though some third-party databases (CB Insights, Growjo) list total funding closer to $66-67 million and Owler lists an outlier figure near $97.2 million -- a discrepancy likely reflecting different treatment of debt/undisclosed tranches or estimate methodology across these secondary sources.

Profile (continued)
By 2020, Rahul Kashyap (former Cylance CTO) had become President & CEO, with Rudolph Araujo serving as VP, Security Product Strategy, Marketing & Business Development. Additional board members reported around the Series C round included cybersecurity industry veteran Kevin Mandia (CEO of FireEye/Mandiant). Sarah Guo, a Greylock partner at the time, is also listed on Crunchbase as an Awake Security board member with a tenure start around November 2014, though this earlier board relationship is less firmly corroborated by primary sources than the 2017 Chandna board seat and 2020 Series C details.
Arista Networks announced its acquisition of Awake Security in 2020. Wikipedia's Arista Networks article dates the deal to October 2020, and Awake's co-founders' professional profiles (per Crunchbase) show their roles transitioning to Arista Networks/Arista NDR titles as of October 2020, with a related Arista 8-K filing made with the SEC on 2020-11-02 -- collectively suggesting the deal likely closed in Q3-Q4 2020. Terms/price of the acquisition were not disclosed in any source reviewed. Post-acquisition, Awake Security's technology and team were integrated into Arista Networks as the 'Arista NDR' (Network Detection and Response) product line, extending Arista's security portfolio. The awakesecurity.com domain now redirects to Arista's security solutions page (arista.com/en/solutions/security), which was independently verified in the course of researching the companion profile_id 10020186.
Competitors in the network detection and response / network traffic analysis space cited for Awake Security include ExtraHop, Vectra AI, Darktrace, LogRhythm, SolarWinds, Lastline, FireEye, and WatchGuard.
DATA QUALITY / SEARCH LIMITATION NOTE: This research session's web-search budget was exhausted before this profile could be researched, so most facts here were carried over and cross-checked from the already-thoroughly-researched companion profile (10020186), supplemented by two live WebFetch verification calls (FinSMEs Series C article and Crunchbase organization page) performed specifically for this row, both of which corroborated the existing data without contradiction. No new facts beyond what was captured in 10020186 were discovered, which is expected since these two rows represent the same real-world company.
