Tenable to Acquire Bit Discovery

Tenable Holdings has announced that it has signed an agreement to acquire Bit Discovery. Combining Tenable’s market-leading Cyber Exposure solutions with Bit Discovery’s EASM capabilities will provide customers with a differentiated 360-degree view of the modern attack surface – both inside out and outside in – to identify and eliminate areas of known and unknown security risk.
Discovering and gaining insight into every part of a business’s digital footprint are essential steps of any effective cybersecurity program. Discovery has never been more critical, given the reliance on critical internet-facing services, applications, and APIs. The problem for most organizations is that they are largely blind to the full and ever-changing scope of internet-facing assets and services. With its powerful EASM solution, Bit Discovery eliminates this problem by continuously monitoring the Internet, allowing customers to rapidly discover and identify all externally facing assets that could become exploitable targets by cybercriminals.
After closing, Tenable will leverage Bit Discovery’s EASM solutions across its entire portfolio – from enterprise vulnerability management (VM) to Nessus, from cloud to operational technology (OT) to identity. Once integrated, customers will have the ability to assess the security posture of their entire attack surface and understand each of these in the context of an attack path that might exist from external systems to critical assets. By covering both external and internal assets, Tenable will provide a comprehensive view of vulnerabilities and cyber risk, allowing customers to prioritize remediation efforts and minimize cyber exposure.
“Whatever is visible on the internet is very likely to be the first target and the hardest thing for organizations to continuously see and assess. We believe attack surface management is vital to modern cybersecurity and an integral part of our vulnerability and Cyber Exposure solutions,” said Glen Pendley, chief technology officer, Tenable. “We are seamlessly combining previously disjointed insights and empowering security practitioners to eliminate blind spots and easily understand their cyber exposure in ways previously not possible.”
“Bit Discovery’s founding mission is to help enterprises identify their internet-facing attack surface area and continually monitor and manage their exposure. Joining Tenable will give us the ability to instantly reach 40,000 global customers, accelerating our vision in ways that would have otherwise been impossible,” said Jeremiah Grossman, CEO, and co-founder of Bit Discovery. “This capability combined with the insights provided by Tenable’s solutions is a compelling chance to change the market.”
Bit Discovery was founded by Jeremiah Grossman and Robert Hansen. Grossman, who also founded WhiteHat Security, has spent approximately 20 years in information security, during which he has become an industry luminary. Hansen previously served as a security pioneer at eBay, where he was responsible for authentication as well as anti-fraud and anti-phishing technologies.
Under the terms of the agreement, Tenable will acquire Bit Discovery for a total purchase price of $44.5 million in cash, subject to customary purchase price adjustments. The acquisition is expected to close later in the second quarter of 2022, subject to the satisfaction of customary closing conditions.
Bit Discovery is not expected to have a significant impact on Tenable’s financial results in the second quarter. For the second half of the year, revenue is not expected to be significant, but Bit Discovery is expected to add $2 million to $3 million of Calculated Current Billings, most notably in the latter part of the year, and $2 million to $3 million of non-GAAP Net Loss.

Versa and OPSWAT Partner to Strengthen SASE Security with Real-Time Device Defense

Versa has announced a strategic technology partnership with OPSWAT to significantly enhance the real-time device security monitoring capabilities of the Versa SASE Client. The Versa SASE Client uniquely combines connectivity and security for users and their devices. It facilitates real-time best-path routing and enforces dynamic security policies based on Zero Trust principles and continuously evaluated device security posture.
Through this partnership, Versa has integrated OPSWAT’s MetaDefender Endpoint Security SDK directly into the Versa SASE Client. This integration empowers IT teams to leverage real-time device posture data, enabling them to automatically validate endpoints and enforce Zero Trust policies, thereby reducing the attack surface.
“Remote workers and BYOD users need access to critical business systems and data; however, this increases organizations’ threat risks if endpoint devices are not secure,” said Anusha Vaidyanathan, Senior Director of Product Management at Versa. “This partnership enables Versa customers to apply OPSWAT’s MetaDefender Endpoint Security SDK directly within our VersaONE Universal SASE Platform. As businesses continue to operate in cloud and hybrid settings, this joint solution enables IT teams to minimize risk by verifying device security and compliance policies before granting access to secure company systems.”
“Our partnership with Versa validates OPSWAT’s commitment to securing critical infrastructure by integrating advanced endpoint compliance capabilities directly into the VersaONE Universal SASE Platform,” said Hamid Karimi, Vice President of Technical Alliances and OEM at OPSWAT. “With OPSWAT MetaDefender Endpoint Security SDK, Versa customers can confidently ensure device compliance and security before network access, providing better defense against today’s evolving cybersecurity threats.”
The MetaDefender SDK is a versatile, cross-platform, and modular framework that serves as a powerful endpoint security software development platform. It enables software engineers and technology vendors to develop advanced endpoint security products. Specifically, the SDK’s Device Compliance Module allows software engineers to implement features for a wide range of applications, including device posture assessment and detection of potentially unwanted applications. This empowers them to deliver enhanced secure remote access, compliance, network access control, remote support, and other critical capabilities to their end customers.

Sophos Boosts Firewall with New Protection and Incident Response Features

Sophos has announced a significant update to its Sophos Firewall software, introducing enhanced protection and incident response capabilities. This update notably includes Sophos NDR Essential, a new feature now available free of charge to all customers holding an XStream Protection license for Sophos Firewall.
This integration empowers Sophos Firewall with two dedicated artificial intelligence (AI) engines specifically designed to detect both malware communications and those utilizing algorithmically generated domain names. This advanced functionality, derived from the Sophos Network Detection and Response (NDR) probe, aims to identify sophisticated malware communications even if they are previously unknown or not yet indexed. It serves as a powerful complement to the Active Threat Response capabilities already embedded within Sophos firewalls.

Chris McCormack, Senior Product Marketing Manager at Sophos
Addressing the technical demands of such advanced detection, Chris McCormack, Senior Product Marketing Manager at Sophos, explained the strategic approach, “NDR traffic analysis requires substantial processing power. That’s why we’ve adopted a new approach by deploying an NDR solution in Sophos Cloud to offload the heaviest tasks from the firewall.” This cloud-centric design ensures optimal performance without burdening the firewall’s on-device resources.
Beyond network detection, the update also brings significant improvements to connectivity and user authentication. Sophos Connect now integrates EntraID for Single Sign-On (SSO). This new feature for the VPN client, bundled with Sophos Firewall, is set to enhance both the security and user experience for SSL and IPsec VPN connections. The integration with EntraID (Azure AD) enables users to authenticate and leverage multi-factor authentication for both Sophos Connect and access to the user portal hosted by the firewall, streamlining secure access.
Further VPN-related enhancements include:
- Improved user interface and usability: Connection types have been renamed for greater clarity, with “site-to-site” now referred to as “policy-based” and tunnel interfaces as “route-based,” making configurations more intuitive.
- Dynamic validation of the IP address pool: For VPN connections (SSL VPN, IPsec, L2TP, and PPTP), the system now dynamically validates the allocated IP address pool, helping to better resolve potential IP address conflicts.
- Strict profile enforcement: IPsec profiles now exclude default values to ensure algorithm synchronization, effectively eliminating potential fragmentation of session negotiation packets that could otherwise prevent site-to-site VPN tunnels from being established.
- Route-based VPN and SD-RED scalability: The system has been optimized to support up to 3,000 simultaneously established tunnels. Specifically, Sophos Firewall solutions can now manage up to 1,000 SD-RED site-to-site tunnels and connect up to 650 concurrent SD-RED devices.
Additional management improvements enhance administrative flexibility and search capabilities:
- More flexible DHCP Prefix Delegation (IPv6 DHCP-PD): The system now supports a broader range of prefixes, from /48 to /64, improving compatibility with various internet service providers.
- Router Advertisement (RA) and DHCPv6 server: These features are now enabled by default, simplifying IPv6 network setup.
- Resizable table columns: The web admin interface continues its adaptation for ultra-wide screens, with many configuration pages now allowing users to resize columns as needed for improved usability.
- Enhanced object search functionality: The search field within the SD-WAN routing configuration screen now supports more granular criteria, including route name, ID, objects, and object values like IP addresses and domains. Similarly, local ACL rules now also support object name and value searches, extending to content-based searches for more precise results.
- Default configuration changes: To streamline initial setups, default firewall rules and rule groups previously created during new firewall deployments have been removed. The initial configuration now only includes the default network rule and MTA rules. Furthermore, the default firewall rule group and the default gateway probe for custom gateways are now set to “None” by default.
Sophos continues its commitment to cybersecurity through a “Secure by Design” approach, enhancing the intrinsic security of its firewalls. This methodology involves the containerization of specific features and rigorous integrity checks on critical operating system files using mathematical checksums. Any detected checksum mismatch triggers a potential compromise alert, enabling monitoring teams to proactively identify possible security incidents affecting the firewall OS integrity. This proactive detection allows incident response and development teams to react swiftly to critical security events.
This update is now available for manual download and deployment by customers with any Sophos Firewall equipped with a valid license.
