Is Secui profitable and what are its revenues?

No audited or DART-sourced revenue figure for Secui has been published as of 2026. Secui is a private subsidiary of Samsung SDS with no disclosed financials, IPO, or funding rounds, consistent with its status as a captive corporate subsidiary rather than an independently reporting company.

Secui Corporation is a subsidiary of Samsung SDS, a relationship confirmed in vendor materials since at least June 2020. This gives Secui distribution access into Samsung's enterprise and government client base, but no independent ownership disclosure or acquisition date has been published.

Could AI replace Secui's core business?

Secui's core manual firewall and SOC-triage workflows are precisely what AI-driven agentic-SOC platforms target. Rivals IGLOO (KISA AI grant, June 2026) and AXGATE (AI NGFW patent, February 2026) are shipping competing automation; Secui's own AI product, TARP, launched only in October 2025 with no verified outcome data.

Is Secui the leading cybersecurity vendor in Korea?

Secui claims (vendor-stated) 13 consecutive years as #1 in Korea's government-procurement network security market as of January 2024. But an independent 2025 survey reported by AhnLab found Secui at 15.2% OT security customer preference versus AhnLab's 24.6%, as of April 2026.

Who is Secui's biggest competitor?

AhnLab is Secui's largest domestic rival, beating it in customer preference across 8 security segments including OT security (24.6% vs 15.2%, April 2026 survey). AXGATE, IGLOO, and SGA Group are also shipping competing AI security features as of 2026.

What is Secui's TARP product?

TARP (Threat Analysis & Response Platform) is Secui's AI-driven threat-response tool, unveiled at the SECUI MAX SUMMIT around October 2025, automating false-positive and true-positive classification and threat prioritization for ransomware and breach response. No independently verified customer outcomes have been published.

Losing its protection

Assessed 26 July 2026 · Evidence as of 26 July 2026

The structural protection is eroding.

On the recordSince 26 July 2026 · Checkable from 2026 to 2028 · Every call on the record Checkpoint: Korean government NGFW procurement refresh cycle where Secui defends its incumbency against AhnLab and AXGATE

The call

Secui still holds its home-turf government contracts, but its AI answer, TARP, launched into a market where AhnLab, IGLOO, and AXGATE are already shipping comparable tools.

Secui makes security software that watches for hackers and responds to threats, mostly sold to Korean government agencies. It's hard to replace because those agencies already use it and trust it, but new AI-powered competitors like IGLOO and AXGATE are doing the same job faster and smarter, which is exactly what Secui's business was built on. The company will either hold its ground in the next round of government contracts starting in 2026, or lose ground to faster rivals.

Why

AI pressure: IGLOO Agentic SOC, AXGATE AI-NGFW, AhnLab XDR. Rivals already ship AI-driven SOC and NGFW tools that match Secui's new TARP platform feature for feature. Could AI do the core job? Yes, likely.

Bigger players: AhnLab. AhnLab now ranks first in customer preference across eight security categories, including the OT segment Secui competes in. Could a giant copy it? Probably.

What protects it. Korean government procurement rules and Samsung SDS backing keep foreign giants like Palo Alto Networks and Fortinet largely out of its core accounts.

What would change this call

Winners of Korea's 2026-2028 government NGFW refresh cycle are disclosed. Shows whether SECUI keeps its 13-year procurement lead or loses share to AhnLab or AXGATE.
Independent adoption or retention data for TARP versus AhnLab XDR or IGLOO Agentic SOC emerges. Shows whether TARP is competitive or lagging domestic AI-threat platforms.
Canon IT Solutions Japan/SE-Asia MSSP rollout reports customer counts within 12 months. Shows whether SECUI's international expansion is gaining real traction or stalling.

Key numbers

Secui claims 13 straight years #1 in Korea gov security procurement (2024-01-22)
AhnLab OT preference 24.6% vs Secui 15.2% in 2025 survey (2026-04-24)
Canon IT Solutions signed as Japan/SE Asia MSSP distributor (2026-02-05)

Named risks

Core appliance and SOC-triage workflows are directly targeted by rival agentic-SOC AI platforms. Severity: high
Losing customer preference to AhnLab in OT security segment despite incumbency claims. Severity: medium
Parent Samsung SDS labor unrest and compensation dispute could affect subsidiary investment priorities. Severity: medium
No independently verified revenue or headcount data creates financial opacity for partners and hires. Severity: medium
New Canon IT Solutions Japan/SE Asia MSSP expansion is early-stage and unproven. Severity: low
