Adtran launches Ensemble Cloudlet vRouter for rapid delivery of enterprise edge services
HUNTSVILLE, Ala.--(BUSINESS WIRE)--Adtran today launched its Ensemble Cloudlet vRouter, a cloud-managed solution that enables providers to deliver high-performance Layer 3 managed services with less cost, complexity and risk. As traditional routers reach end-of-life and core network revenues remain flat, providers are looking to enterprise sites to drive new growth. Delivered through a single subscription, the new solution offers a lower-cost alternative to proprietary appliances while enabling smarter service delivery, faster rollout and improved monetization of enterprise connectivity at the network edge. By replacing locked, single-function routers with a flexible virtualized platform, it gives providers a simpler, more powerful way to modernize their edge infrastructure. Our new Ensemble Cloudlet vRouter offers an immediate way to modernize services, increase margins and support high-value business customers with greater agility. Share 'The economics of enterprise service delivery are shifting rapidly – and providers can't afford to stand still,' said Robert Conger, GM of software platforms and strategy at Adtran. 'Our new Ensemble Cloudlet vRouter offers an immediate way to modernize services, increase margins and support high-value business customers with greater agility. It delivers the simplicity of a traditional appliance while also bringing the scalability and intelligence of a cloud-native platform. Many providers are stuck managing legacy appliances that are expensive to evaluate, deploy and scale. With this solution, they can break free of those constraints and confidently expand their service capabilities over time.' Adtran's Ensemble Cloudlet vRouter combines servers with high-performance virtual routing technology powered by 6WIND, alongside centralized cloud orchestration via Ensemble EdgeView. With native support for 2.5Gbit/s, 10Gbit/s SFP+ and optional 5G wireless, it delivers dynamic Layer 3 routing, VPN, DNS, DHCP, QoS, stateful firewall capabilities and robust IPsec security. The platform offers zero-touch provisioning, remote lifecycle management and cloud-hosted orchestration services for faster time to market and streamlined operations. Providers can scale up from 4-core systems for routing-only use cases to 8-core configurations that support additional virtual network functions and enterprise workloads.

Cloudflare Sees Record Spike in DDoS Attacks in Q1 2025
Home » Emerging technologies » Cyber Security » Cloudflare Sees Record Spike in DDoS Attacks in Q1 2025 Cloudflare, Inc., the security, performance, and reliability company, has released its Q1 2025 DDoS report. The report highlights trends and insights from one of the world's largest global networks. The findings point to a sharp rise in DDoS attacks across industries and regions. In just the first quarter of 2025, Cloudflare mitigated 20.5 million DDoS attacks. This figure nearly matches the total for all of 2024, which stood at 21.3 million. The company's autonomous systems blocked 96% of the previous year's total volume in just three months. Network-layer attacks surged the most. Cloudflare mitigated 16.8 million such attacks in Q1 2025. That's a 397% increase quarter-over-quarter and a 509% increase year-over-year. HTTP DDoS attacks rose by 7% QoQ and 118% YoY. Hyper-volumetric attacks have become more frequent. Cloudflare blocked over 700 attacks exceeding 1 Tbps or 1 billion packets per second (Bpps). On average, it faced eight of these per day. Most were UDP-based and classified as network-layer DDoS. Key observations: About 4 in 100,000 network-layer attacks were hyper-volumetric. 6 in 100 HTTP DDoS attacks exceeded 1 million requests per second (rps). 99% of L3/4 attacks remained under 1 Gbps and 1M pps. 94% of HTTP DDoS attacks were below 1M rps. Most attacks were short. 89% of network-layer and 75% of HTTP DDoS attacks ended within 10 minutes. Some of the largest attacks lasted just a minute, leaving little time for human response. Cloudflare identified Germany as the top target in Q1. The country jumped four spots to take first place. Turkey surged 11 positions to second. China dropped to third. Meanwhile, Hong Kong became the top source of DDoS attacks, followed by Indonesia and Argentina. New attack vectors also gained traction. CLDAP reflection attacks saw a 3,488% QoQ increase. CLDAP, a UDP-based variant of LDAP, enables IP spoofing and is being abused for amplification. ESP reflection attacks rose by 2,301% QoQ. ESP, part of the IPsec protocol, can be exploited if misconfigured systems are targeted. Industries affected the most in Q1 include: Gambling & Casinos (top target, up 4 spots) Telecommunications (second place) Information Technology & Services Internet Gaming The Airlines, Aviation & Aerospace sector had the largest leap, moving up 40 positions to enter the top 10. The top five source countries for DDoS attacks were: Hong Kong Indonesia Argentina Singapore Ukraine Bashar Bashaireh, AVP Middle East, Türkiye & North Africa at Cloudflare, stated, 'Many organizations still adopt DDoS protection only after an incident or rely on outdated solutions. Our data shows that proactive, always-on strategies are more effective. That's why we focus on automation and in-line protection, powered by our 348 Tbps global network.' Cloudflare's findings underline a shift in the cyber threat landscape. The scale, speed, and volume of DDoS attacks continue to increase. Businesses are urged to adopt real-time, automated protection to remain resilient.

The best VPN service for 2025
Securing your online footprint can seem like a daunting task. We've become accustomed to giving up bits of data for convenience, and have been forced into trusting our internet service providers because access has become so vital to everyday life. You don't have to blindly accept this, though: using a virtual private network (VPN) can be an easy way to gain back some of your anonymity and security while browsing online. Still, it can be challenging to differentiate which service makes most sense for your online tested nine of the most popular VPN services available now to come up with our top picks, and lay out what you should know before paying for one. Our top pick remains ProtonVPN thanks to its easy-to-use interface, no-logs policy and open-source framework, while other popular options like NordVPN didn't quite make the cut. While we think ProtonVPN is the best VPN for most people, we lay out other good options you can consider, too. Best VPNs of 2025 What is a VPN? Are VPNs worth it? How we tested VPNs Other VPN services our experts tested VPN FAQs VPNs, or virtual private networks, mask your IP address and the identity of your computer or mobile device on the network and creating an encrypted "tunnel" that prevents your internet service provider (ISP) from accessing data about your browsing history. VPNs are not a one-size-fits-all security solution, though. Instead, they're just one part of keeping your data private and secure. Roya Ensafi, assistant professor of computer science and engineering at the University of Michigan, told Engadget that VPNs don't protect against common threats like phishing attacks, nor do they protect your data from being stolen. Much of the data or information is stored with the VPN provider instead of your ISP, which means that using a poorly designed or unprotected network can still undermine your security. But they do come in handy for online privacy when you're connecting to an untrusted network somewhere public because they tunnel and encrypt your traffic to the next hop. That means sweeping claims that seem promising, like military-grade encryption or total digital invisibility, may not be totally accurate. Instead, Yael Grauer, program manager of Consumer Reports' online security guide, recommends looking for security features like open-source software with reproducible builds, up-to-date support for industry-standard protocols like WireGuard (CR's preferred protocol) or IPsec, and the ability to defend against attack vectors like brute force. How to use a VPN on your iPhone How to stream video to your TV using a VPN How to stream using a VPN on your Google TV or Chromecast How to stream via a VPN on Roku Before considering a VPN, make sure your online security is up to date in other ways. That means complex passwords, multi-factor authentication methods and locking down your data sharing preferences. Even then, you probably don't need to be using a VPN all the time. 'If you're just worried about somebody sitting there passively and looking at your data then a VPN is great,' Jed Crandall, an associate professor at Arizona State University, told Engadget. That brings us to some of the most common uses cases for VPNs. If you use public WiFi networks a lot, like while working at a coffee shop, then VPN usage can help give you private internet access. They're also helpful for hiding information from other people on your ISP if you don't want members of your household to know what you're up to online. Geoblocking has also become a popular use case as it helps you reach services in other parts of the world. For example, you can access shows that are only available on streaming services, like Netflix, Hulu or Amazon Prime, in other countries, or play online games with people located all over the globe. There are also a few common VPN features that you should consider before deciding if you want to use one, and which is best for you: Split tunneling allows you to route some traffic through your VPN, while other traffic has direct access to the internet. This can come in handy when you want to protect certain activity online without losing access to local network devices, or services that work best with location sharing enabled. A double VPN, otherwise known as multi-hop VPN or a VPN chain, passes your online activity through two different VPN servers one right after the other. For VPN services that support this, users are typically able to choose which two servers they want their traffic to pass through. As you might expect, this provides an extra layer of security. Whether or not VPNs are worth it depends how often you could use it for the above use cases. If you travel a lot and rely on public WiFi or hotspots, are looking to browse outside of your home country or want to keep your traffic hidden from your ISP, then investing in a VPN will be useful. But, keep in mind that even the best VPN services often slow down your internet connection speed, so they may not be ideal all the time. In today's world, we recommend not relying on a VPN connection as your main cybersecurity tool. VPN use can provide a false sense of security, leaving you vulnerable to attack. Plus, if you choose just any VPN, it may not be as secure as just relying on your ISP. That's because the VPN could be based in a country with weaker data privacy regulation, obligated to hand information over to law enforcement or linked to weak user data protection policies. For VPN users working in professions like activism or journalism that want to really strengthen their internet security, options like the Tor browser may be a worthwhile alternative, according to Crandall. Tor is free, and while it's less user-friendly, it's built for anonymity and privacy. To test the security specs of different VPNs and name our top picks, we relied on pre-existing academic work through Consumer Reports, VPNalyzer and other sources. We referenced privacy policies, transparency reports and security audits made available to the public. We also considered past security incidents like data breaches. We looked at price, usage limits, effects on internet speed, possible use cases, ease of use, general functionality and additional 'extra' VPN features like multihop. The VPNs were tested across iOS, Android and Mac devices so we could see the state of the mobile apps across various platforms (Windows devices are also supported in most cases). We used the 'quick connect' feature on the VPN apps to connect to the 'fastest' provider available when testing internet speed, access to IP address data and DNS and WebRTC leaks or when a fault in the encrypted tunnel reveals requests to an ISP. Otherwise, we conducted a test of geoblocking content by accessing Canada-exclusive Netflix releases, a streaming test by watching a news livestream on YouTube via a Hong Kong-based VPN and a gaming test by playing on servers in the United Kingdom. By performing these tests at the same time, it also allowed us to test claims about simultaneous device use. Here are the VPN services we tested: ExpressVPN NordVPN Surfshark Proton VPN TunnelBear Bitdefender VPN CyberGhost Windscribe Atlas VPN Read more: The best password managers for 2023 NordVPN didn't quite make the cut because it's overhyped, and underwhelming. As I've written in our full review of NordVPN, the pricing, up to $14.49 for a 'complete' subscription, seemed high compared to other services, and its free or lower cost plans just didn't have the same wide variety of features as its competitors. Despite the cute graphics and user friendliness, TunnelBear wasn't a top choice. It failed numerous basic security tests from Consumer Reports, and had limited availability across platforms like Linux. It did, however, get a major security boost in July when it updated to support WireGuard protocol across more of its platforms. Bitdefender doesn't offer support for devices like routers, which limits its cross-platform accessibility. It also lacked a transparency report or third-party audit to confirm security specs. Atlas ranked lower on our speed tests compared to the other VPNs tested, with a notably slower difference on web browsing and streaming tests. It was a good option otherwise, but could easily cause headaches for those chasing high speed connections. Security-wise, an Atlas VPN vulnerability leaked Linux users' real IP addresses. VPNs are traditionally used to protect your internet traffic. If you're connected to an untrusted network like public WiFi in a cafe, using a VPN hides what you do from the internet service provider. Then, the owner of the WiFi or hackers trying to get into the system can't see the identity of your computer or your browsing history. A common non-textbook use case for VPNs has been accessing geographically restricted content. VPNs can mask your location, so even if you're based in the United States, they can make it appear as if you're browsing abroad and unblock access. This is especially useful for streaming content that's often limited to certain countries, like if you want to watch Canadian Netflix from the US. A VPN doesn't hide all of your data. It only hides information like your IP address, location and browser history. A common misconception is that VPNs can make you totally invisible online. But keep in mind that the VPN provider often still has access to all of this information, so it doesn't grant you total anonymity. You're also still vulnerable to phishing attacks, hacking and other cyberthreats that you should be mindful of by implementing strong passwords and multi-factor authentication. Generally, yes. VPNs are a safe and reliable way to encrypt and protect your internet data. But like most online services, the safety specifics vary from provider to provider. You can use resources like third-party audits, Consumer Reports reviews, transparency reports and privacy policies to understand the specifics of your chosen provider. Yes, you can use a VPN on your phone. Most major VPN services have mobile apps you can install on iPhones and Android devices so you can connect on your phone to protect your mobile browsing. Google One subscriptions include access to the company's VPN, which works similarly to other VPNs on our list, hiding your online activity from network operators. However, Google announced recently that it plans to shut down the One VPN because "people simply weren't using it." There's no specific date for the shutdown, with Google simply saying it will discontinue the service sometime in 2024. Pixel phone owners, however, will continue to have access to the free VPN available on their devices. October 2024: Added a "read more" section with links to additional VPN content.
