Cybersecurity: Sophos launches “Xstream” version of XG Firewall

Sophos , a global leader in next-generation cybersecurity, has introduced a new “Xstream” architecture for Sophos XG Firewall with high performance Transport Layer Security (TLS) traffic decryption capabilities that eliminate significant security risk associated with encrypted network traffic, which is often overlooked by security teams due to performance and complexity concerns.
XG Firewall now also features AI-enhanced threat analysis from SophosLabs and accelerated application performance.
Sophos also published the SophosLabs Uncut article, “Nearly a Quarter of Malware now Communicates Using TLS,” which explains how 23% of malware families use encrypted communication for Command and Control (C2) or installation.
The article details, for example, three common and ever-present Trojans – Trickbot, IcedID and Dridex – that leverage TLS during the course of their attacks.
Cybercriminals also use TLS to hide their exploits, payloads and stolen content and to avoid detection. In fact, 44% of prevalent information stealers use encryption to sneak hijacked data, including bank and financial account passwords and other sensitive credentials, out from under organizations.
Dan Schiappa, chief product officer at Sophos, said “As SophosLabs’ research demonstrates, cybercriminals are boldly embracing encryption in an attempt to bypass security products.
“Unfortunately, most firewalls lack scalable TLS crypto capabilities and are unable to inspect encrypted traffic without causing applications to break or degrade network performance.
“With the new Xstream architecture in XG Firewall, Sophos is providing critical visibility into an enormous blind spot while eliminating frustrating latency and compatibility issues with full support for the latest TLS 1.3 standard.
“Sophos’ internal benchmark tests have clocked a two-fold performance boost in the new XG TLS inspection engine as compared to previous XG versions. This is a game changer.”
Latency too often deters IT admins from using decryption, as seen in an independent Sophos survey of 3,100 IT managers in 12 countries. The survey white paper, The Achilles Heel of Next-Gen Firewalls, reports that while 82% of respondents agreed TLS inspection is necessary, only 3.5% of organizations are decrypting their traffic to properly inspect it.
Sophos listed Key new features of XG Firewall to include:
• Inspection of TLS 1.3 to detect cloaked malware: New port-agnostic TLS engine doubles crypto operation performance over previous XG versions
• Optimized critical application performance: New FastPath policy controls accelerate performance of SD-WAN applications and traffic, including Voice over IP, SaaS and others, to up to wire speed
• Adaptive traffic scanning: The newly enhanced Deep Packet Inspection (DPI) engine dynamically risk-assesses traffic streams and matches them to the appropriate threat scanning level, enhancing throughput by up to 33% across most network environments
• Threat analysis with SophosLabs intelligence: Provides network administrators with the SophosLabs AI-enhanced threat analysis needed to understand and adjust defenses to protect against a constantly changing threat landscape
• Comprehensive cloud management and reporting in Sophos Central: Centralized management and reporting capabilities in Sophos Central provide customers with group firewall management and flexible cloud reporting across an entire estate without additional charge
• Integration with Sophos Managed Threat Response (MTR) service: Customers of XG Firewall who also subscribe to the Sophos MTR Advanced service will have deeper actionable intelligence to prevent, detect and respond to threats, as a result of the integration
“Sophos’ new XG Firewall offers a wide array of enterprise-caliber features, with a growing installed base that is now one of the industry’s most widely deployed next-generation firewalls,” Eric Parizo, senior analyst for enterprise IT strategy, (according to Omdia, Enterprise Decision Maker, January 2020. Results are not an endorsement of Sophos or SophosLabs. Any reliance on these results is at the third-party’s own risk).
“XG Firewall can win against industry competitors in large part because of Sophos Central, its SaaS-based, single-pane-of-glass management system for overseeing deployment, management, policy, updates, and response, with optional log management and analytics. This cloud management platform with the Firewall Management and Reporting feature, plus the TLS inspection, position Sophos XG Firewall as a compelling option for a wide variety of organizations.
Bruce Kneece, CTO of Columbia, S.C.-based Convergent Information Security Solutions said, “At Convergent Information Security Solutions, we are engaged in the management and monitoring of both perimeter and internal cybersecurity for our customers, and until now we were somewhat limited in our ability to monitor SSL/TLS encrypted data streams.
“Sophos XG Firewall helps us solve this problem efficiently and affordably with the new accelerated DPI engine in the latest version.
“This, combined with new automatically-managed custom IPS rule sets, gives us much more visibility into encrypted traffic going through the network than we ever had before.
“This feature will immensely improve our customers’ security and we consider this to be critical, based how broadly cybercriminals are capitalizing on TLS encryption to cover-up and carry out their attacks.
“We’re also aware of how fast cyberattacks are morphing. With the ability to scan for potentially dangerous files transported inside of SSL/TLS tunnels, in addition to the zero-day detection engine of Sandstorm, we can provide better, faster customer protection, detection and service.”
Sophos XG Firewall is available in the cloud-based Sophos Central platform alongside Sophos’ entire portfolio of next-generation cybersecurity solutions.
Sophos’ unique Synchronized Security approach empowers these solutions to work together for real-time information sharing and threat response.

Airtel Africa Extends $100M Share Buyback Plan

Airtel Africa has extended its $100 million share buyback programme, first launched in December 2024, in partnership with Barclays Capital Securities Limited. The scheme, aimed at improving shareholder returns, has so far returned $34.7 million through the repurchase of 14.2 million shares, with $20.3 million still to be acquired.
The initiative, now running until March 2026, follows the completion of an initial $50 million phase in April 2025 and currently includes a $55 million tranche.
The telecommunications group, listed on the Nigerian Exchange (NGX), is operating within regulations that restrict share buybacks to 15 percent of issued shares over two years. All repurchased shares will be cancelled, reducing the company’s share capital and potentially increasing earnings per share (EPS).
The buyback follows a strong performance in the first quarter of 2025, when Airtel Africa reported a 16-fold increase in EPS to 3.4 cents, supported by higher operating profits and lower foreign exchange losses. The company also raised capital expenditure by 27 percent, investing $737 million in 2024 to expand infrastructure and secure spectrum across its markets.
The extension of the scheme, according to Airtel Africa, also reflects its intention to provide consistent shareholder value while maintaining investment in its network. The partnership with Barclays ensures compliance with regulations during closed trading periods and seeks to limit market disruption.
Airtel Africa has in recent years considered a separate listing of its mobile money business but postponed the initial public offering in 2025, choosing instead to direct capital into shareholder-focused measures such as the buyback.
Industry observers point out that buybacks may improve financial ratios by reducing outstanding shares, but they can also indicate fewer reinvestment options. Airtel Africa has argued that its programme complements long-term growth priorities, pointing to a 29.5 percent increase in mobile money revenue and a 24 percent rise in its customer base.
The company continues to weigh shareholder rewards alongside reinvestment, citing foreign exchange volatility and other economic pressures in its largest market, Nigeria.

Stakeholders Chart Strategic Path for MVNOs in Nigeria

A decisive call for collaboration, strategic market positioning, and patient capital has been issued by key players in Nigeria’s telecommunications sector to unlock the dormant potential of Mobile Virtual Network Operators (MVNOs).
The resolution emerged from the sixth edition of the Telecoms Sector Sustainability Forum (TSSF) organised by Business Remarks at Ikeja, Lagos State, where stakeholders convened under the theme: Unlocking Nigeria’s MVNO Potential: Status, Trends, Investment, and Future Prospects.
The forum, which brought together major mobile network operators (MNOs), the Nigerian Communications Commission (NCC), and licensed MVNOs, served as a candid platform to diagnose the critical challenges stifling the growth of the MVNO sub-sector. The forum stressed that the sustainability of MVNOs in Nigeria is a collective responsibility. It called for unwavering collaboration between MNOs, the NCC, and the MVNOs to replicate the success stories seen in other nations, ultimately fostering a more diverse, competitive, and inclusive telecommunications market for all Nigerians.
In his keynote address, the Executive Vice Chairman of the Nigerian Communication Commission, NCC, Dr. Aminu Maida said the entrance of MVNOs is expected to provide competitive niche offerings as well as enhance digital communications ecosystem in Nigeria for the benefit of the subscribers and the Nigerian economy.
Ably represented by the Director of Licensing and Authorisation, Mr Usman Mamman, NCC noted that there are now over 1000 MVNOs globally, with more than 500 operating in Europe alone and 46 MVNO Licenses were issued in Nigeria by the regulator in the year 2023.
Addressing stakeholders, Maida stated that the Commission is not oblivion to the challenges faced by MVNOs in Nigeria, particularly in relation to commercial negotiations. He therefore pledged that NCC is working assiduously with Mobile Network Operators (MNOs) to improve network capacity.
Furthermore, NCC’s EVC encouraged MNOs to partner with MVNOs to target new verticals, drive margin growth as well as to monetize spare capacity, while urging MVNOs players to recognise the viability of the Nigerian market, invest boldly, and position themselves to reap the long-term benefits of their investments.
In his speech, the President of the Association of Telecommunications Companies of Nigeria (ATCON), Mr Tony Izuagbe Emoekpere, dissuaded MVNO Licensees from blindly adopting foreign MVNOs model for Nigerian local market and consumers. He urged players to conduct diligent market analysis and focus on service differentiation through specialized offerings. “MVNOs need to carve a unique niche specially designed for the Nigerian market,” Emoekpere said.
Speaking on this, the co-founder and executive director, Infratel Africa, Dr Tola Yusuf, stressed that MVNOs in Nigeria’s market must adopt a more strategic approach to succeed in rural and underserved areas. Categorically noting that there are immense potential in connecting these rural communities, Yusuf argued that MVNOs often focus on urban, high-density areas like Lagos, neglecting the vast majority of the population, estimated at over 25 million people who remain completely unconnected.
“The true winners in the MVNO space will be those who develop a clear strategy to serve these markets, even if it requires significant logistical effort, such as using horses or boats to reach remote communities,” he said. He also suggested that the current market might see future mergers and acquisitions, with some license holders potentially selling their licenses as they fail to compete effectively.
Citing examples of banks with MVNOs licenses in other climes, NCC’s Director of Licensing and Authorisation, Mr Usman Mamman during the panel session draws attention to how financial institutions have successfully entered the telecom space by understanding its customers’ needs and tailoring holistic lifestyle services accordingly.
While addressing the need to focus on providing niche services to specific customer groups, Mamman noted that unlike large mobile network operators, MVNOs are expected to be digital-first and flexible, which enables them to be innovative and quickly capitalize on underserved market segments.
On his part, the Director USK Mobile, Dr Chidi Ajuzie, called attention to the capacity constraints by the host MNOs and the revenue- sharing model that can limit profitability. Ajuzie
According to him, “Tier 5 MVNOs are expected to build their own core infrastructure and billing systems (BSS/OSS), but they still rely on the MNO’s radio access network. This creates a bottleneck. Even if a Tier 5 MVNO has excellent billing systems, it can’t offer unlimited data or guaranteed high speeds if the MNO’s network is already at capacity,” he stated.
Ajuzie, however, said some higher-tier are now looking for innovative ways to go beyond the constraint by securing acquiring additional licenses, such as Internet Service Provider (ISP) or Public Licence (PL) licenses.
He also emphasized the
need for a significant expansion of the existing infrastructure, particularly by MVNOs who are now integrating their own fixed infrastructure, such as fiber networks. This expansion, he says, is the only way to “expand the pipe” and create a truly competitive and viable market for all players.
Also speaking ipNX Director of Startegic Business Initiative, Mr Olusola Teniola argued that the nation’s 40,000 telecom towers are grossly insufficient for a population of over 200 million, especially when compared to the United Kingdom’s 75,000 towers for a much smaller population. He stated that unlike developed nations where public funds initially built a robust telecom backbone, Nigeria’s infrastructure was financed by a few dominant mobile network operators (MNOs) who have invested billions.
Teniola posited that the lack of widespread infrastructure, particularly outside major cities like Lagos, Abuja, and Port Harcourt, presents a major challenge for new MVNOs, which were intended to serve the millions of unconnected Nigerians, particularly in rural areas. He also warned that without substantial new investment to expand the network, the MVNO business model will struggle to succeed, with only those that can survive a long-term, 7-to-10-year investment cycle likely to see a return on their capital.
In her welcome address, the Convener who also doubles as the Managing Editor of Business Remarks, Bukola Olanrewaju, said the Nigerian telecom market is growing at an incredible pace and the level of success recorded in each country with MVNOs is largely dependent on the regulatory enforcement and interventions, wholesale agreement, spectrum access, and on how effectively MVNOs players can navigate these hurdles.
“To succeed, Nigeria must collectively build an ecosystem that is both competitive and sustainable,” Olanrewaju remarked as she brought into focus MVNOs operations in South Africa, Thailand and Argentina.
The forum, TSSF 6.0, stressed that the sustainability of MVNOs in Nigeria is a collective responsibility. It called for unwavering collaboration between MNOs, the NCC, and the MVNOs themselves to replicate the success stories seen in other nations, ultimately fostering a more diverse, competitive, and inclusive telecommunications market for all Nigerians.

Airtel AI Blocks 84 Percent of Spam SMS in Nigeria

Nigeria has recorded an 84 Percent decline in spam SMS after Airtel Africa deployed its Artificial Intelligence-powered spam detection tool, Spam Alert.
According to Airtel, the free service has flagged over 205 million fraudulent and unsolicited messages across 13 African markets within six months.
Nigeria registered the sharpest decline, while Kenya recorded the highest flagged spam volume with 68 million messages, followed by Tanzania with 47 million and Zambia with 33 million.
Spam Alert prefixes suspicious SMS with “SPAM Alert,” providing users with real-time protection against phishing scams and nuisance texts without requiring extra applications.
Sunil Taldar, CEO, Airtel Africa, said the solution demonstrates the company’s commitment to tackling digital fraud as smartphone penetration expands across Africa.
Currently active in 13 of Airtel’s 14 markets, including Nigeria, Uganda, Zambia, and Tanzania, the service has cut overall spam SMS by 12% across the continent. Seychelles will join soon, Airtel confirmed.
In Nigeria, Airtel reported that between March 13 and May 20, 2025, the system intercepted more than 9.6 million suspicious messages, of which over 9.1 million originated from off-network sources. T
he AI-powered system scans all SMS in real-time using 250 parameters, including sender identity, link structure, and regional anomalies, processing each message in under two milliseconds without storing content.
The Nigerian Communications Commission (NCC) welcomed the innovation.
Dr. Aminu Maida, executive vice chairman, said the initiative strengthens consumer protection at a time when spam and fraud are growing more sophisticated. He stressed the need for more collaboration between operators and regulators to reduce digital risks.
The NCC’s 2023 Industry Risk Report had ranked phishing and bulk unsolicited messaging among the top threats facing subscribers, especially in rural areas and among first-time smartphone users.
Airtel’s initiative is expected to ease these concerns by reinforcing trust in mobile communications.
