What the Index is not

Not a prediction. It describes assessed conditions today, not what will happen tomorrow.
Not personal security advice. Your own risk depends on your location, profile, and movements.
Not an official or government source. It is CIS's professional assessment, published freely.
Not a substitute for emergency services. In an emergency, contact the competent authorities.

Correction protocol: material scoring errors are corrected and noted in the daily record.

CIS LEBANON SECURITY INDEX - August 18 2026

⬇️ EASING BY DECAY, BAND FALLS TO HIGH — The national alert level reads 79/100 HIGH, set by Nabatieh and down six points from 85 as Saturday's mass-casualty day ages out of the seven-day window.

15 August 2026 13 min

CIS LEBANON SECURITY INDEX - August 15 2026

⬆️⬆️ SHARPLY RISING — CIS must report the deadliest single Israeli attack on Lebanon since the truce that took hold in June.

14 August 2026 11 min

CIS LEBANON SECURITY INDEX - August 14 2026

↔️ STABLE — CIS must open today's update with a correction to its own prior reporting.

13 August 2026 16 min

CIS LEBANON SECURITY INDEX - August 13 2026

⬆️ SLIGHT DETERIORATION — CIS is elevating its index by one point today to reflect what is, in CIS's assessment, the most significant political development of the past week: a public, on-the-record rebuke from the Trump administration to its own security partner.

12 August 2026 15 min

CIS LEBANON SECURITY INDEX - August 12 2026

↔️ STABLE, WITH A SERIOUS NEW ACCOUNTABILITY DIMENSION — CIS is incorporating today a major finding that sharpens the legal stakes of this conflict considerably: Human Rights Watch, Amnesty International, and the Lebanese rights group The Legal Agenda released separate investigations concluding that Israel's April 22 killing of veteran Lebanese journalist Amal Khalil in al-Tiri, southern Lebanon, was very likely an intentional, targeted killing that constitutes a war crime, compounded by a deliberate, hours-long obstruction of rescuers that a postmortem examination suggests may have cost Khalil her life.

11 August 2026 17 min

CIS LEBANON SECURITY INDEX - August 11 2026

↔️ HOLDING AT SEVERE LEVEL, WITH A NOTABLE OFFICIAL CLAIM OF UNDERLYING IMPROVEMENT — CIS is holding its assessment in the HIGH-CRITICAL band across this reporting window (August 9-11), balancing two genuinely different pictures presented by the same set of facts.

10 August 2026 13 min

CIS LEBANON SECURITY INDEX - August 10 2026

⬆️ RISING SHARPLY — CIS must report today that the pattern of continued Israeli military activity, which UNIFIL first quantified for CIS on August 3, has now escalated to its highest documented level.

9 August 2026 16 min

CIS LEBANON SECURITY INDEX - August 9 2026

↔️ HOLDING AT SEVERE LEVEL, WITH GENUINELY MIXED SIGNALS — CIS is holding its assessment at a severely elevated level over this three-day reporting window (August 7-9), with countervailing developments pulling in different directions.

8 August 2026 12 min

CIS LEBANON SECURITY INDEX - August 8 2026

↔️ STABLE BUT CONTRADICTORY — CIS must report a genuinely striking incident today: Israeli troops infiltrated Zawtar al-Gharbiyeh overnight — the single village CIS has tracked most closely as the framework's proof-of-concept success story since its July 21 handover — and built a new earthen barrier roughly 100 meters from the town square, blocking a road at the village's eastern entrance.

7 August 2026 15 min

CIS LEBANON SECURITY INDEX - August 7 2026

⬆️ RISING — CIS must report a significant and unambiguous military escalation today.

6 August 2026 12 min

CIS LEBANON SECURITY INDEX - August 6 2026

↔️ STABLE TO SLIGHTLY EASING — The seventh round of US-brokered Israel-Lebanon talks, running Tuesday through today in Rome, appears more substantive than prior rounds in its actual agenda — but reportedly no closer to a breakthrough.

5 August 2026 13 min

CIS LEBANON SECURITY INDEX - August 5 2026

⬆️⬆️ SHARPLY RISING — CIS is raising its assessment materially today, from 70 to 78, reflecting the most serious single military escalation CIS has recorded since the ceasefire took hold on June 20.

4 August 2026 14 min

CIS LEBANON SECURITY INDEX - August 4 2026

⬇️ EASING (LEBANON TRACK, CAUTIOUSLY) — CIS is moderating its assessment slightly today, from 73 to 70, while maintaining the HIGH band.

3 August 2026 13 min

CIS LEBANON SECURITY INDEX - August 3 2026

⬆️ RISING, WITH THE UN'S OWN DATA NOW CONFIRMING THE SCALE CIS HAS BEEN TRACKING QUALITATIVELY — For the first time in several weeks, the United Nations itself has published hard numbers that corroborate the pattern of continued, high-tempo Israeli military activity CIS has documented location-by-location throughout this index.

2 August 2026 15 min

CIS LEBANON SECURITY INDEX - August 2 2026

⬆️ RISING (LEBANON TRACK) / ⬇️ EASING (WIDER REGIONAL IRAN TRACK) — CIS is tracking two distinct and currently diverging trend lines this morning.

1 August 2026 14 min

CIS LEBANON SECURITY INDEX - August 1 2026

⬆️⬆️ SHARPLY RISING — CIS must open today's update with the broader regional context, because it now directly bears on the risk calculus for Lebanon: Iranian ballistic missiles struck the Israeli towns of Arad and Dimona overnight, wounding nearly 200 people — by far the largest single Israeli civilian casualty toll CIS has recorded from this reignited war — and multiple outlets report President Trump has ordered new strikes aimed at forcing Iran's "surrender," with a fresh US offensive reportedly able to begin as soon as this weekend and last several days.

31 July 2026 15 min

CIS LEBANON SECURITY INDEX - July 31 2026

⬆️ RISING — CIS's assessment from yesterday has been directly confirmed: Israel has retaliated for Wednesday's Hezbollah drone strike.

30 July 2026 14 min

CIS LEBANON SECURITY INDEX - July 30 2026

⬆️ RISING — Today marks a genuine inflection point CIS must flag clearly: for the first time since the ceasefire took hold, the Israeli military has accused Hezbollah of an actual offensive action rather than the reverse.

29 July 2026 13 min

CIS LEBANON SECURITY INDEX - July 29 2026

↔️ STABLE, WITH GENUINELY COMPETING SIGNALS — Today brings CIS's first confirmed, concrete evidence that the pilot-zone disarmament mechanism is actually functioning as designed: the Lebanese Army discovered a Hezbollah weapons cache during operations in one of the pilot-zone areas, with the joint US-Lebanon-Israel coordination mechanism formally notified and Israeli sources independently confirming the find.

28 July 2026 12 min

CIS LEBANON SECURITY INDEX - July 28 2026

↔️ STABLE — Today brings a direct clash between the diplomatic narrative CIS has tracked since last week's Zawtar al-Gharbiyeh handover and Hezbollah's own detailed counter-account of what actually happened.

27 July 2026 13 min

CIS LEBANON SECURITY INDEX - July 27 2026

↔️ STABLE, WITH COMPETING SIGNALS — Today brings the first tangible sign that yesterday's Lebanese Army complaint about pilot-zone "obstruction" has not stopped the process entirely: residents of Zawtar al-Gharbiyeh have begun returning to their homes following the Lebanese Army's deployment there, per live monitoring of the area.
