PLDT Enterprise, the corporate arm of PLDT, is partnering with global cloud communications platform Infobip to enhance SMS security for its subscribers. By integrating Infobip's advanced Anam Protect Firewall solution into Smart Communications Inc. (Smart)'s network, PLDT is reinforcing its commitment to delivering innovative and secure solutions for its customers.

The integration of the Anam Protect Firewall has reduced the incidence of spam and smishing experienced by Smart subscribers, ensuring a safer cyber space environment for customers. Leveraging Infobip’s expertise as the leading omnichannel firewall provider—ranked number one by Rocco for several consecutive years—this solution sets a benchmark for both person-to-person (P2P) and application-to-person (A2P) messaging security.

The Anam Protect Firewall is hosted within PLDT Enterprise’s infrastructure, utilizing state-of-the-art VITRO Data Centers for maximum security and redundancy. This advanced setup enables faster SMS delivery, improved network efficiency, and an enhanced user experience while protecting subscribers from fraudulent messaging practices.

Since the implementation of Anam Firewall in Smart’s network, it has successfully blocked over 1.3 billion instances of spam, SIM farm activities, and fraud attempts targeting Smart subscribers from August 2024 to January 2025—enhancing network security and safeguarding customers from digital threats.

Infobip’s expertise in the messaging space, bolstered by its global footprint and technical capabilities, made it a natural partner for this initiative. “This partnership underscores our continuing commitment to solutions that matter. By working with Infobip, we are ensuring that Smart’s network delivers not only speed and reliability but also unparalleled security for our customers,” said Josh Montecillo, Assistant Vice President and Head of Enterprise and International Wireless Product Management at PLDT Enterprise.

The Anam Protect Firewall brings to the table industry-leading capabilities that address the rising concerns of smishing and spam. “We are honored to be a trusted partner of PLDT on multiple levels for over a decade, securing all mobile end users under the PLDT and Smart umbrella. This partnership reinforces our shared commitment to spearheading the fight against fraud and spam. The number of blocked attempts is clear proof that we are tackling a real problem and addressing it in the best possible way," said Goran Valjak, Telecom Business Director at Infobip.

Backed by PLDT Enterprise’s unparalleled network and data center capabilities, Infobip’s Anam Protect Firewall solution is designed to handle high transaction throughput efficiently, ensuring subscribers receive their messages faster and with enhanced security. By integrating this solution, PLDT Enterprise continues to lead the way in digital innovation while addressing a growing need for safer communication platforms.

In addition, businesses can seamlessly switch to Smart’s secure and reliable 5G and 4G network through Mobile Number Portability while retaining their existing numbers. This ensures a smooth transition, allowing enterprises to benefit from Smart’s enhanced network coverage, robust security features, and superior customer support.

This initiative also aligns with the PLDT group’s broader sustainability and innovation goals specifically SDG 9 – Industry, Innovation, and Infrastructure. The growing partnership emphasizes the company’s dedication to creating technology-driven solutions that foster a secure and sustainable digital ecosystem for communities and businesses alike across the nation.​
