New Study Shows Email Accounts for One‑Third of Managed Security Service Analyses, Prompting Faster Phishing Triage at Tier‑1

A recent industry analysis has found that email now represents almost one in three security investigations performed by managed security service providers (MSSPs), underscoring the growing burden of phishing on frontline analysts.

Tier‑1 analysts, who serve as the first line of defense in MSSP operations, are tasked with quickly determining whether a suspicious message is a genuine threat or a false alarm. Historically, limited visibility into the latest adversary tactics has slowed this decision‑making process, extending the time it takes to isolate malicious traffic.

According to the report, the introduction of interactive analysis platforms—tools that let analysts manipulate data in real time—combined with constantly refreshed threat‑intelligence feeds, is dramatically shortening that window. Clearer evidence, such as automatically extracted indicators of compromise, allows Tier‑1 staff to confirm phishing attempts with far fewer manual steps.

Once a potential phishing incident is verified, the enhanced workflow ensures a seamless handoff to Tier‑2 specialists, regardless of geographic location. The study notes that coordinated, worldwide handoffs reduce duplication of effort and help maintain a consistent response posture across the provider’s global client base.

The speed gains matter because phishing remains one of the most prevalent cyber‑attack vectors, responsible for a large share of data breaches and financial loss. Faster triage limits the window attackers have to harvest credentials or deploy ransomware, ultimately protecting both the MSSP’s customers and its own reputation.

Looking ahead, the findings suggest that MSSPs will likely double down on automation, real‑time intelligence sharing, and cross‑regional collaboration to keep pace with evolving email‑based threats. By equipping Tier‑1 teams with better tools and clearer evidence, providers aim to stay ahead of attackers and deliver more reliable protection to their clients.
